The main focus of this volume is on the problem of describing the automorphism groups of affine and projective varieties, a classical subject in algebraic geometry where, in both cases, the automorphism group is often infinite dimensional. The collection covers a wide range of topics and is intended for researchers in the fields of classical algebraic geometry and birational geometry (Cremona groups) as well as affine geometry with an emphasis on algebraic group actions and automorphism groups. It presents original research and surveys and provides a valuable overview of the current state of the art in these topics. Bringing together specialists from projective, birational algebraic geometry and affine and complex algebraic geometry, including Mori theory and algebraic group actions, this book is the result of ensuing talks and discussions from the conference "Groups of Automorphisms in Birational and Affine Geometry" held in October 2012, at the CIRM, Levico Terme, Italy. The talks at the conference highlighted the close connections between the above-mentioned areas and promoted the exchange of knowledge and methods from adjacent fields.

Featuring a blend of original research papers and comprehensive surveys from an international team of leading researchers in the thriving fields of foliation theory, holomorphic foliations, and birational geometry, this book presents the proceedings of the conference "Foliation Theory in Algebraic Geometry," hosted by the Simons Foundation in New York City in September 2013. Topics covered include: Fano and del Pezzo foliations; the cone theorem and rank one foliations; the structure of symmetric differentials on a smooth complex surface and a local structure theorem for closed symmetric differentials of rank two; an overview of lifting symmetric differentials from varieties with canonical singularities and the applications to the classification of AT bundles on singular varieties; an overview of the powerful theory of the variety of minimal rational tangents introduced by Hwang and Mok; recent examples of varieties which are hyperbolic and yet the Green-Griffiths locus is the whole of X; and a classification of psuedoeffective codimension one distributions. Foliations play a fundamental role in algebraic geometry, for example in the proof of abundance for threefolds and to a solution of the Green-Griffiths conjecture for surfaces of general type with positive Segre class. The purpose of this volume is to foster communication and enable interactions between experts who work on holomorphic foliations and birational geometry, and to bring together leading researchers to demonstrate the powerful connection of ideas, methods, and goals shared by these two areas of study.

A handbook of research techniques for teachers, this book documents the historical development and changing nature of action research in the curriculum and aims to encourage teacher development through curriculum inquiry. It describes 57 action research tools, ten of which are new.

Curriculum and Imagination describes an alternative 'process' model for designing developing, implementing and evaluating curriculum, suggesting that curriculum may be designed by specifying an educational process which contains key principles of procedure.

This comprehensive and authoritative book:

• offers a practical and theoretical plan for curriculum-making without objectives
• shows that a curriculum can be best planned and developed at school level by teachers adopting an action research role
• complements the spirit and reality of much of the teaching profession today, embracing the fact that there is a degree of intuition and critical judgement in the work of educators
• presents empirical evidence on teachers' human values.

Curriculum and Imagination provides a rational and logical alternative for all educators who plan curriculum but do not wish to be held captive by a mechanistic 'ends-means' notion of educational planning. Anyone studying or teaching curriculum studies, or involved in education or educational planning, will find this important new book fascinating reading.

Training in how to undertake practical research (referred to as action research) is not usually part of teacher training. Moreover, this book argues that curriculum inquiry belongs to the practitioner who is best placed to research his or her own practice. Obviously the teacher or lecturer is ill-equipped to conduct such research without the vital tools.;This book describes 57 of these action research tools - at least ten of which are developed and offered for the first time. Additionally, the author documents the historical development and changing nature of action research in the curriculum and encourages teacher development through curriculum inquiry.

Algebraic geometry is one of the most diverse fields of research in mathematics. It has had an incredible evolution over the past century, with new subfields constantly branching off and spectacular progress in certain directions, and at the same time, with many fundamental unsolved problems still to be tackled. In the spring of 2009 the first main workshop of the MSRI algebraic geometry program served as an introductory panorama of current progress in the field, addressed to both beginners and experts. This volume reflects that spirit, offering expository overviews of the state of the art in many areas of algebraic geometry. Prerequisites are kept to a minimum, making the book accessible to a broad range of mathematicians. Many chapters present approaches to long-standing open problems by means of modern techniques currently under development and contain questions and conjectures to help spur future research.
