Book Description
The fundamental problem in control engineering is to provide robust performance to uncertain plants. H -control theory began in the early eighties as an attempt to lay down rigorous foundations on the classical robust control requirements. It now turns out that H -control theory is at the crossroads of several important directions of research space or polynomial approach to control and classical interpolation theory; harmonic analysis and operator theory; minimax LQ stochastic control and integral equations. The book presents the underlying fundamental ideas, problems and advances through the pen of leading contributors to the field, for graduate students and researchers in both engineering and mathematics. From the Contents: C. Foias: Commutant Lifting Techniques for Computing Optimal H Controllers.- B.A. Francis: Lectures on H Control and Sampled-Data Systems.- J.W. Helton: Two Topics in Systems Engineering Frequency Domain Design and Nonlinear System.- H. Kwakernaak: The Polynomial Approach to H -Optimal Regulation.- J.B.

Book Description
This volume gives an overview of the recent representative developments in relativistic and non-relativistic quantum theory, which are related to the application of various mathematical notions of various symmetries. These notions are centered upon groups, algebras and their generalizations, and are applied in interaction with topology, differential geometry, functional analysis and related fields. The emphasis is on results in the following areas: foundation of quantum physics, quantization methods, nonlinear quantum mechanics, algebraic quantum field theory, gauge and string theories, discrete spaces, quantum groups and generalized symmetries.

Book Description
About ten years ago, V.D. Goppa found a surprising connection between the theory of algebraic curves over a finite field and error-correcting codes. The aim of the meeting "Algebraic Geometry and Coding Theory" was to give a survey on the present state of research in this field and related topics. The proceedings contain research papers on several aspects of the theory, among them: Codes constructed from special curves and from higher-dimensional varieties, Decoding of algebraic geometric codes, Trace codes, Exponen- tial sums, Fast multiplication in finite fields, Asymptotic number of points on algebraic curves, Sphere packings.

Book Description
At a time of potentially radical changes in the ways in which humans interact with their environments - through financial, environmental and/or social crises - the raison d'être of spatial planning faces significant conceptual and empirical challenges. This Companion presents a multidimensional collection of critical narratives of conceptual challenges for spatial planning. The authors draw on various disciplinary traditions and theoretical frames to explore different ways of conceptualising spatial planning and the challenges it faces. Through problematising planning itself, the values which underpin planning and theory-practice relations, contributions make visible the limits of established planning theories and illustrate how, by thinking about new issues, or about issues in new ways, spatial planning might be advanced both theoretically and practically. There cannot be definitive answers to the conceptual challenges posed, but the authors in this collection provoke critical questions and debates over important issues for spatial planning and its future. A key question is not so much what planning theory is, but what might planning theory do in times of uncertainty and complexity. An underlying rationale is that planning theory and practice are intrinsically connected. The Companion is presented in three linked parts: issues which arise from an interactive understanding of the relations between planning ideas and the political-institutional contexts in which such ideas are put to work; key concepts in current theorising from mainly poststructuralist perspectives and what discussion on complexity may offer planning theory and practice.

Lie Algebras: Definition and Examples Let Ie be a commutativering with unit element, and let A be a k-module, then A is said to be a Ie-algebra if there is given a k-bilinear map A x A~ A (i.e., a k-homomorphism A0" A -+ A). As usual we may define left, right and two-sided ideals and therefore quo tients. Definition 1. A Lie algebra over Ie isan algebrawith the following properties: 1).

Book Description
The final aim of the book is to construct effective discretization methods to solve multidimensional weakly singular integral equations of the second kind on a region of Rn e.g. equations arising in the radiation transfer theory. To this end, the smoothness of the solution is examined proposing sharp estimates of the growth of the derivatives of the solution near the boundary G. The superconvergence effect of collocation methods at the collocation points is established. This is a book for graduate students and researchers in the fields of analysis, integral equations, mathematical physics and numerical methods. No special knowledge beyond standard undergraduate courses is assumed.
