One-Cocycles and Knot Invariants is about classical knots, i.e.,
smooth oriented knots in 3-space. It introduces discrete
combinatorial analysis in knot theory in order to solve a global
tetrahedron equation. This new technique is then used to construct
combinatorial 1-cocycles in a certain moduli space of knot
diagrams. The construction of the moduli space makes use of the
meridian and the longitude of the knot. The combinatorial
1-cocycles are therefore lifts of the well-known Conway polynomial
of knots, and they can be calculated in polynomial time. The
1-cocycles can distinguish loops consisting of knot diagrams in the
moduli space up to homology. They give knot invariants when they
are evaluated on canonical loops in the connected components of the
moduli space. They are a first candidate for numerical knot
invariants which can perhaps distinguish the orientation of knots.
This book is the third of a three-volume set of books on the theory
of algebras, a study that provides a consistent framework for
understanding algebraic systems, including groups, rings, modules,
semigroups and lattices. Volume I, first published in the 1980s,
built the foundations of the theory and is considered to be a
classic in this field. The long-awaited volumes II and III are now
available. Taken together, the three volumes provide a
comprehensive picture of the state of art in general algebra today,
and serve as a valuable resource for anyone working in the general
theory of algebraic systems or in related fields. The two new
volumes are arranged around six themes first introduced in Volume
I. Volume II covers the Classification of Varieties, Equational
Logic, and Rudiments of Model Theory, and Volume III covers Finite
Algebras and their Clones, Abstract Clone Theory, and the
Commutator. These topics are presented in six chapters with
independent expositions, but are linked by themes and motifs that
run through all three volumes.
This book discusses, analyzes, and reflects on how "self-different"
fractals can create and change innovation. Concentrating on the
potential benefits and opportunities that self-different fractals
have on innovating systems, this book provides academic researchers
and practitioners with the knowledge of how competing and
contradictory principles co-produce the productive chaos that
causes change, development, and evolution to occur. Covering both
linear and non-linear designs, the authors will analyze the way
selfdifferent fractals promote innovation and how creative designs
are not only possible, but also necessary for the innovation system
that drives society and social systems.

This monograph provides a coherent development of operads, infinity
operads, and monoidal categories, equipped with equivariant
structures encoded by an action operad. A group operad is a planar
operad with an action operad equivariant structure. In the first
three parts of this monograph, we establish a foundation for group
operads and for their higher coherent analogues called infinity
group operads. Examples include planar, symmetric, braided, ribbon,
and cactus operads, and their infinity analogues. For example, with
the tools developed here, we observe that the coherent ribbon nerve
of the universal cover of the framed little 2-disc operad is an
infinity ribbon operad.In Part 4 we define general monoidal
categories equipped with an action operad equivariant structure and
provide a unifying treatment of coherence and strictification for
them. Examples of such monoidal categories include symmetric,
braided, ribbon, and coboundary monoidal categories, which
naturally arise in the representation theory of quantum groups and
of coboundary Hopf algebras and in the theory of crystals of finite
dimensional complex reductive Lie algebras.
The study of the geometry of structures that arise in a variety of
specific natural systems, such as chemical, physical, biological,
and geological, revealed the existence of a wide range of types of
polytopes of the highest dimension that were unknown in classical
geometry. At the same time, new properties of polytopes were
discovered as well as the geometric patterns to which they obey.
There is a need to classify these types of polytopes of the highest
dimension by listing their properties and formulating the laws to
which they obey. The Classes of Higher Dimensional Polytopes in
Chemical, Physical, and Biological Systems explains the meaning of
higher dimensions and systematically generalizes the results of
geometric research in various fields of knowledge. This book is
useful both for the fundamental development of geometry and for the
development of branches of science related to human activities. It
builds upon previous books published by the author on this topic.
Covering areas such as heredity, geometry, and dimensions, this
reference work is ideal for researchers, scholars, academicians,
practitioners, industry professionals, instructors, and students.
Mathematical Methods of Analytical Mechanics uses tensor geometry
and geometry of variation calculation, includes the properties
associated with Noether's theorem, and highlights methods of
integration, including Jacobi's method, which is deduced. In
addition, the book covers the Maupertuis principle that looks at
the conservation of energy of material systems and how it leads to
quantum mechanics. Finally, the book deduces the various spaces
underlying the analytical mechanics which lead to the Poisson
algebra and the symplectic geometry.
The book presents a comprehensive overview of various aspects of
three-dimensional geometry that can be experienced on a daily
basis. By covering the wide range of topics - from the psychology
of spatial perception to the principles of 3D modelling and
printing, from the invention of perspective by Renaissance artists
to the art of Origami, from polyhedral shapes to the theory of
knots, from patterns in space to the problem of optimal packing,
and from the problems of cartography to the geometry of solar and
lunar eclipses - this book provides deep insight into phenomena
related to the geometry of space and exposes incredible nuances
that can enrich our lives.The book is aimed at the general
readership and provides more than 420 color illustrations that
support the explanations and replace formal mathematical arguments
with clear graphical representations.
