This book provides the mathematical foundations for Feynman's
operator calculus and for the Feynman path integral formulation of
quantum mechanics as a natural extension of analysis and functional
analysis to the infinite-dimensional setting. In one application,
the results are used to prove the last two remaining conjectures of
Freeman Dyson for quantum electrodynamics. In another application,
the results are used to unify methods and weaken domain
requirements for non-autonomous evolution equations. Other
applications include a general theory of Lebesgue measure on Banach
spaces with a Schauder basis and a new approach to the structure
theory of operators on uniformly convex Banach spaces. This book is
intended for advanced graduate students and researchers.
The present volume contains the Proceedings of the International
Conference on Spectral Theory and Mathematical Physics held in
Santiago de Chile in November 2014. Main topics are: Ergodic
Quantum Hamiltonians, Magnetic Schroedinger Operators, Quantum
Field Theory, Quantum Integrable Systems, Scattering Theory,
Semiclassical and Microlocal Analysis, Spectral Shift Function and
Quantum Resonances. The book presents survey articles as well as
original research papers on these topics. It will be of interest to
researchers and graduate students in Mathematics and Mathematical
Physics.
The book discusses three classes of problems: the generalized Nash
equilibrium problems, the bilevel problems and the mathematical
programming with equilibrium constraints (MPEC). These problems
interact through their mathematical analysis as well as their
applications. The primary aim of the book is to present the modern
tool of variational analysis and optimization, which are used to
analyze these three classes of problems. All contributing authors
are respected academicians, scientists and researchers from around
the globe. These contributions are based on the lectures delivered
by experts at CIMPA School, held at the University of Delhi, India,
from 25 November-6 December 2013, and peer-reviewed by
international experts. The book contains five chapters. Chapter 1
deals with nonsmooth, nonconvex bilevel optimization problems whose
feasible set is described by using the graph of the solution set
mapping of a parametric optimization problem. Chapter 2 describes a
constraint qualification to MPECs considered as an application of
calmness concept of multifunctions and is used to derive
M-stationarity conditions for MPEC. Chapter 3 discusses the first-
and second-order optimality conditions derived for a special case
of a bilevel optimization problem in which the constraint set of
the lower level problem is described as a general compact convex
set. Chapter 4 concentrates the results of the modelization and
analysis of deregulated electricity markets with a focus on
auctions and mechanism design. Chapter 5 focuses on optimization
approaches called reflection methods for protein conformation
determination within the framework of matrix completion. The last
chapter (Chap. 6) deals with the single-valuedness of quasimonotone
maps by using the concept of single-directionality with a special
focus on the case of the normal operator of lower semi-continuous
quasiconvex functions.
This book explains - in simple terms and with almost no mathematics
- the physics behind recent and glamorous discoveries in Cosmology,
Quantum Mechanics, Elementary Particles (e.g. Higgs bosons) and
Complexity Theory. En route it delves into the historical landmarks
and revolutions that brought about our current understanding of the
universe. The book is written mainly for those with little
scientific background, both college students and lay readers alike,
who are curious about the world of modern physics. Unsolved
problems are highlighted and the philosophical implications of the
sometimes astounding modern discoveries are discussed. Along the
way the reader gains an insight into the mindset and methodology of
a physicist.
This textbook takes the reader on a tour of the most important
landmarks of theoretical physics: classical, quantum, and
statistical mechanics, relativity, electrodynamics, as well as the
most modern and exciting of all: elementary particles and the
physics of fractals. The second edition has been supplemented with
a new chapter devoted to concise though complete presentation of
dynamical systems, bifurcations and chaos theory. The treatment is
confined to the essentials of each area, presenting all the central
concepts and equations at an accessible level. Chapters 1 to 4
contain the standard material of courses in theoretical physics and
are supposed to accompany lectures at the university; thus they are
rather condensed. They are supposed to fill one year of teaching.
Chapters 5 and 6, in contrast, are written less condensed since
this material may not be part of standard lectures and thus could
be studied without the help of a university teacher. An appendix on
elementary particles lies somewhere in between: It could be a
summary of a much more detailed course, or studied without such a
course. Illustrations and numerous problems round off this unusual
textbook. It will ideally accompany the students all along their
course in theoretical physics and prove indispensable in preparing
and revising the exams. It is also suited as a reference for
teachers or scientists from other disciplines who are interested in
the topic.
Gradiometry is a multidisciplinary area that combines theoretical
and applied physics, ultra-low noise electronics, precision
engineering, and advanced signal processing. All physical fields
have spatial gradients that fall with distance from their sources
more rapidly than the field strength itself. This makes the
gradient measurements more difficult. However, there has been a
considerable investment, both in terms of time and money, into the
development of various types of gradiometers driven by the
extremely valuable type of information that is contained in
gradients. Applications include the search for oil, gas, and
mineral resources, GPS-free navigation, defence, space missions,
medical research, and some other applications. The author describes
gravity gradiometers, magnetic gradiometers, and electromagnetic
(EM) gradiometers. The first two types do not require any active
sources of the primary physical fields whose gradients are
measured, such as gravity field and ambient magnetic field. EM
gradiometers do require a primary EM field, pulsed, or sinusoidal,
which propagates through media and creates a secondary EM field.
The latter one contains information about the non uniformness of
electromagnetically active media such as conductivity and magnetic
permeability contrasts. These anomalies are the boundaries of
mineral deposits, oil and gas traps, underground water reserves,
buried artifacts, unexploded ordnance (UXO), nuclear submarines,
and even cancerous human tissue. This book provides readers with a
comprehensive introduction, history, potential applications, and
current developments in relation to some of the most advanced
technologies in the 21st Century. Most of the developments are
strictly controlled by Defence Export Control rules and
regulations, introduced in all developed countries that typically
require permission to transfer relevant information from one
country to another. The book is based on the materials that have
been available in public domain such as scientific journals,
conferences, extended abstracts, and online presentations. In
addition, medical applications of EM gradiometers are exempt from
any control, and some new results relevant to breast cancer early
detection research are published in this book for the first time.
This book presents a selection of the best contributions to GIREP
EPEC 2015, the Conference of the International Research Group on
Physics Teaching (GIREP) and the European Physical Society's
Physics Education Division (EPS PED). It introduces readers
interested in the field to the problem of identifying strategies
and tools to improve physics teaching and learning so as to convey
Key Competences and help students acquire them. The main topic of
the conference was Key Competences (KC) in physics teaching and
learning in the form of knowledge, skills and attitudes that are
fundamental for every member of society. Given the role of physics
as a field strongly connected not only to digital competence but
also to several other Key Competences, this conference provided a
forum for in-depth discussions of related issues.
This book is an exploration of philosophical questions about
infinity. Graham Oppy examines how the infinite lurks everywhere,
both in science and in our ordinary thoughts about the world. He
also analyses the many puzzles and paradoxes that follow in the
train of the infinite. Even simple notions, such as counting,
adding and maximising present serious difficulties. Other topics
examined include the nature of space and time, infinities in
physical science, infinities in theories of probability and
decision, the nature of part/whole relations, mathematical theories
of the infinite, and infinite regression and principles of
sufficient reason.
This volume presents the proceedings of the 11th Conference on
Problems and Methods in Mathematical Physics (11th TMP), held in
Chemnitz, March 25-28, 1999. The conference was dedicated to the
memory of Siegfried PrAssdorf, who made important contributions to
the theory and numerical analysis of operator equations and their
applications in mathematical physics and mechanics. The main part
of the book comprises original research papers. The topics are
ranging from integral and pseudodifferential equations, boundary
value problems, operator theory, boundary element and wavelet
methods, approximation theory and inverse problems to various
concrete problems and applications in physics and engineering, and
reflect PrAssdorf's broad spectrum of research activities. The
volume also contains articles describing the life and mathematical
achievements of Siegfried PrAssdorf and includes a list of his
publications. The book is addressed to a wide audience in the
mathematical and engineering sciences.
This book introduces the fundamentals of computer vision (CV), with
a focus on extracting useful information from digital images and
videos. Including a wealth of methods used in detecting and
classifying image objects and their shapes, it is the first book to
apply a trio of tools (computational geometry, topology and
algorithms) in solving CV problems, shape tracking in image object
recognition and detecting the repetition of shapes in single images
and video frames. Computational geometry provides a visualization
of topological structures such as neighborhoods of points embedded
in images, while image topology supplies us with structures useful
in the analysis and classification of image regions. Algorithms
provide a practical, step-by-step means of viewing image
structures. The implementations of CV methods in Matlab and
Mathematica, classification of chapter problems with the symbols
(easily solved) and (challenging) and its extensive glossary of key
words, examples and connections with the fabric of CV make the book
an invaluable resource for advanced undergraduate and first year
graduate students in Engineering, Computer Science or Applied
Mathematics. It offers insights into the design of CV experiments,
inclusion of image processing methods in CV projects, as well as
the reconstruction and interpretation of recorded natural scenes.
Measurement is an essential activity in every branch of technology
and science, the fourth edition of this successful text has been
extensively extended and updated to include new developments in
measurement devices and technology. Principles of Measurement
Systems, 4/e provides a coherent and integrated approach to the
topic, covering the main techniques and devices used, together with
relevant theory applications, for both mechanical and electronic
systems.
An increasing complexity of models used to predict real-world
systems leads to the need for algorithms to replace complex models
with far simpler ones, while preserving the accuracy of the
predictions. This three-volume handbook covers methods as well as
applications. This third volume focuses on applications in
engineering, biomedical engineering, computational physics and
computer science.
This book is based on the idea that Boltzmann-like modelling
methods can be developed to design, with special attention to
applied sciences, kinetic-type models which are called generalized
kinetic models. In particular, these models appear in evolution
equations for the statistical distribution over the physical state
of each individual of a large population. The evolution is
determined both by interactions among individuals and by external
actions.
Considering that generalized kinetic models can play an
important role in dealing with several interesting systems in
applied sciences, the book provides a unified presentation of this
topic with direct reference to modelling, mathematical statement of
problems, qualitative and computational analysis, and applications.
Models reported and proposed in the book refer to several fields of
natural, applied and technological sciences. In particular, the
following classes of models are discussed: population dynamics and
socio-economic behaviours, models of aggregation and fragmentation
phenomena, models of biology and immunology, traffic flow models,
models of mixtures and particles undergoing classic and dissipative
interactions.

This book advocates the importance and value of errors for the
progress of scientific research! Hans Kricheldorf explains that
most of the great scientific achievements are based on an iterative
process (an 'innate self-healing mechanism'): errors are committed,
being checked over and over again, through which finally new
findings and knowledge can arise. New ideas are often first
confronted with refusal. This is so not only in real life, but also
in scientific and medical research. The author outlines in this
book how great ideas had to ripen over time before winning
recognition and being accepted. The book showcases in an
entertaining way, but without schadenfreude, that even some of the
most famous discoverers may appear in completely different light,
when regarding errors they have committed in their work. This book
is divided into two parts. The first part creates a fundament for
the discussion and understanding by introducing important concepts,
terms and definitions, such as (natural) sciences and scientific
research, laws of nature, paradigm shift, and progress (in
science). It compares natural sciences with other scientific
disciplines, such as historical research or sociology, and examines
the question if scientific research can generate knowledge of
permanent validity. The second part contains a collection of famous
fallacies and errors from medicine, biology, chemistry, physics and
geology, and how they were corrected. Readers will be astonished
and intrigued what meanders had to be explored in some cases before
scientists realized facts, which are today's standard and
state-of-the-art of science and technology. This is an entertaining
and amusing, but also highly informative book not only for
scientists and specialists, but for everybody interested in
science, research, their progress, and their history!
This book focuses on the theory of the Zakharov system in the
context of plasma physics. It has been over 40 years since the
system was first derived by V. E. Zakharov - and in the course of
those decades, many innovative achievements with major impacts on
other research fields have been made. The book represents a first
attempt to highlight the mathematical theories that are most
important to researchers, including the existence and unique
problems, blow-up, low regularity, large time behavior and the
singular limit. Rather than attempting to examine every aspect of
the Zakharov system in detail, it provides an effective road map to
help readers access the frontier of studies on this system.
This book offers a timely overview of fractional calculus
applications, with a special emphasis on fractional derivatives
with Mittag-Leffler kernel. The different contributions, written by
applied mathematicians, physicists and engineers, offers a snapshot
of recent research in the field, highlighting the current
methodological frameworks together with applications in different
fields of science and engineering, such as chemistry, mechanics,
epidemiology and more. It is intended as a timely guide and source
of inspiration for graduate students and researchers in the
above-mentioned areas.
