There has in recent years been a remarkable growth of interest in the area of discrete integrable systems. Much progress has been made by applying symmetry groups to the study of differential equations, and connections have been made to other topics such as numerical methods, cellular automata and mathematical physics. This volume comprises state of the art articles from almost all the leading workers in this important and rapidly developing area, making it a necessary resource for all researchers interested in discrete integrable systems or related subjects.

This volume contains eleven contributions by invited speakers at the annual Logic Colloquium which was held in San Sebastian, Spain, in July 1996. They cover model theory, proof theory, recursion and complexity theory, logic for artificial intelligence and formal semantics of natural languages, and include both recent results and survey articles on the central topics in logic written by specialists for a wide audience.

Presents a cross-section of different aspects of Riemann surfaces, introducing the reader to the basics as well as highlighting new developments in the field. It provides a mixture of classical material, recent results and some non-mainstream topics. The book is based on lectures from the conference Topics on Riemann Surfaces and Fuchsian Groups held in Madrid to mark the 25th anniversary of the Universidad Nacional de Educación a Distancia. For those wishing to pursue research in this area, this volume offers a valuable summary of contemporary thought and a source of fresh geometric and algebraic insights. The book will be suitable for graduate courses, as well as providing a useful reference for those already working in geometry, group theory, complex analysis, algebraic geometry, topology and theoretical physics.

This wide-ranging collection brings together views about the nature of 'English' and its users at an unusual time. Within the United Kingdom - and in some other countries - there is a feeling of unease that language and literacy are in decline and that their central role in developing a sense of national unity and heritage is weakening. Governmental response to this perception is to move towards centralized, state-imposed curricula and assessment, seeking to guarantee standards through legislation. At the same time that the original source of English feels insecure, other countries and cultures become increasingly confident about taking over its use and ownership on their own terms and within their own cultures. Several of the authors here celebrate the diverse ways in which people across the world are developing their own distinctive varieties of English. In exploring these contradictory, defensive and optimistic attitudes towards the inevitability of linguistic and cultural change, the volume's contributors demonstrate the current liveliness and intensity of discussion about this perennial and increasingly debated topic.

A rich variety of real-life physical problems which are still poorly understood are of a nonlinear nature. Examples include turbulence, granular flows, detonations and flame propagation, fracture dynamics, and a wealth of new biological and chemical phenomena which are being discovered. Particularly interesting among the manifestations of nonlinearity are coherent structures. This book contains reviews and contributions reporting on the state of the art regarding the role of coherent structures and patterns in nonlinear science.
