Methods in Nonlinear Integral Equations

September 2002, ISBN 1-4020-0844-9, Hardbound

Methods in Nonlinear Integral Equations presents several extremely fruitful methods for the analysis of systems and nonlinear integral equations. They include: fixed point methods (the Schauder and Leray-Schauder principles), variational methods (direct variational methods and mountain pass theorems), and iterative methods (the discrete continuation principle, upper and lower solutions techniques, Newton's method and the generalized quasilinearization method). Many important applications for several classes of integral equations and, in particular, for initial and boundary value problems, are presented to complement the theory. Special attention is paid to the existence and localization of solutions in bounded domains such as balls and order intervals. The presentation is essentially self-contained and leads the reader from classical concepts to current ideas and methods of nonlinear analysis.

This work will be of interest to graduate students and theoretical and applied mathematicians in nonlinear functional analysis, integral equations, ordinary and partial differential equations, and related fields.

Differential Topology and General Equilibrium
with Complete and Incomplete Markets

August 2002, ISBN 1-4020-7201-5, Hardbound

The goal of this publication is to provide basic tools of differential topology to study systems of nonlinear equations, and to apply them to the analysis of general equilibrium models with complete and incomplete markets. The main content of general equilibrium analysis is to study existence, (local) uniqueness and efficiency of equilibria. To study existence Differential Topology and General Equilibrium with Complete and Incomplete Markets combines two features. First, order conditions (of agents' maximization problems) and market clearing conditions, instead of aggregate excess demand functions. Then the application to that "extended system" of a homotopy argument, which is stated and proved in relatively elementary manner. Local uniqueness and smooth dependence of the endogenous variables from the exogenous ones are studied using a version of a so called parametric transversality theorem. In a standard general equilibrium model, all equilibria are efficient, but that is not the case if some imperfection, like incomplete markets, asymmetric information, strategic interaction, is added. Then, for almost all economies, equilibria are inefficient, and an outside institution can Pareto improve upon the market outcome. Those results are proved showing that a well-chosen system of equations has no solutions.

The target audience of Differential Topology and General Equilibrium with Complete and Incomplete Markets consists of researchers interested in economic theory. The needed background is multivariate analysis, basic linear algebra and basic general topology.

Stochastic Approximation and Its Application

September 2002, ISBN 1-4020-0806-6, Hardbound

This book presents the recent development of stochastic approximation algorithms with expanding truncations based on the TS (trajectory-subsequence) method, a newly developed method for convergence analysis. This approach is so powerful that conditions used for guaranteeing convergence have been considerably weakened in comparison with those applied in the classical probability and ODE methods. The general convergence theorem is presented for sample paths and is proved in a purely deterministic way. The sample-path description of theorems is particularly convenient for applications. Convergence theory takes both observation noise and structural error of the regression function into consideration. Convergence rates, asymptotic normality and other asymptotic properties are presented as well. Applications of the developed theory to global optimization, blind channel identification, adaptive filtering, system parameter identification, adaptive stabilization and other problems arising from engineering fields are demonstrated.

Audience: Researchers and students of both graduate and undergraduate levels in systems and control, optimization, signal processing, communication and statistics.

Speech Acts, Mind, and Social Reality
Discussions with John R. Searle

September 2002, ISBN 1-4020-0853-8, Hardbound

Book Series: STUDIES IN LINGUISTICS AND PHILOSOPHY : Volume 79

Speech Acts, Mind, and Social Reality - these are the main topics in the work of John R. Searle, one of the leading philosophical figures of the present times. How language is based on intentionality, how intentionality in turn is to be explicated by means of distinctions discovered in Speech Act Theory, and how language and intentionality are both related to social facts and institutions - these are questions to be tackled in this volume. The contributions result from discussions on and with John R. Searle, containing Searle's own latest views - including his seminal ideas on Rationality in Action. The collection provides a good basis for advanced seminar debates in Philosophy of Language, Philosophy of Mind, and Social Philosophy, and will also stimulate some further research on all of the three main topics.

Evolutionary Algorithms for Embedded System Design

October 2002, ISBN 1-4020-7276-7, Hardbound

Book Series: GENETIC ALGORITHMS AND EVOLUTIONARY COMPUTATION : Volume 10

Evolutionary Algorithms for Embedded System Design describes how Evolutionary Algorithm (EA) concepts can be applied to circuit and system design - an area where time-to-market demands are critical. EAs create an interesting alternative to other approaches since they can be scaled with the problem size and can be easily run on parallel computer systems. This book presents several successful EA techniques and shows how they can be applied at different levels of the design process. Starting on a high-level abstraction, where software components are dominant, several optimization steps are demonstrated, including DSP code optimization and test generation. Throughout the book, EAs are tested on real-world applications and on large problem instances. For each application the main criteria for the successful application in the corresponding domain are discussed. In addition, contributions from leading international researchers provide the reader with a variety of perspectives, including a special focus on the combination of EAs with problem specific heuristics.

Evolutionary Algorithms for Embedded System Design is an excellent reference for both practitioners working in the area of circuit and system design and for researchers in the field of evolutionary concepts.
