Focusing on the asymptotic behavior of solutions in cylindrical domains, this book addresses the challenges of proving that solutions become uniform across cross-sections as the cylinder's size approaches infinity. It offers rigorous proofs for various significant cases involving linear and nonlinear problems within the realm of elliptic and parabolic partial differential equations, thereby filling a notable gap in existing literature and enhancing understanding of these complex mathematical theories.
Focusing on the theory of elliptic partial differential equations, this book presents complex topics in an accessible manner, steering clear of intricate technical details. It covers a range of subjects including singular perturbations, homogenization, asymptotic behavior, and elliptic systems. The text also addresses nonlinear problems, regularity theory, and various operator types while minimizing discussions on Sobolev spaces and boundary integration. This approach highlights the beauty and diversity of the subject, making it engaging for readers.
The aim of this book is to introduce the reader to different topics of the theory of elliptic partial differential equations by avoiding technicalities and refinements. Apart from the basic theory of equations in divergence form it includes subjects such as singular perturbation problems, homogenization, computations, asymptotic behaviour of problems in cylinders, elliptic systems, nonlinear problems, regularity theory, Navier-Stokes system, p-Laplace equation. Just a minimum on Sobolev spaces has been introduced, and work or integration on the boundary has been carefully avoided to keep the reader's attention on the beauty and variety of these issues. The chapters are relatively independent of each other and can be read or taught separately. Numerous results presented here are original and have not been published elsewhere. The book will be of interest to graduate students and faculty members specializing in partial differential equations.
The present volume is dedicated to celebrate the work of the renowned mathematician Herbert Amann, who had a significant and decisive influence in shaping Nonlinear Analysis. The 32 contributions cover a wide range of nonlinear elliptic and parabolic equations with applications to natural sciences and engineering.
This book provides proofs of the asymptotic behavior of solutions to various important cases of linear and nonlinear problems in the theory of elliptic and parabolic partial differential equations. It is a valuable resource for graduates and researchers in applied mathematics and for engineers. Many results presented here have not been published elsewhere. They will motivate and enable the reader to apply the theory to other problems in partial differential equations.
The goal of this book is to present some modern aspects of nonlinear analysis. Some of the material introduced is classical, some more exotic. We have tried to emphasize simple cases and ideas more than complicated refinements. Also, as far as possible, we present proofs that are not classical or not available in the usual literature. Of course, only a small part of nonlinear analysis is covered. Our hope is that the reader - with the help of these notes - can rapidly access the many different aspects of the field. We start by introducing two physical issues: elasticity and diffusion. The pre sentation here is original and self contained, and helps to motivate all the rest of the book. Then we turn to some theoretical material in analysis that will be needed throughout (Chapter 2). The next six chapters are devoted to various aspects of elliptic problems. Starting with the basics of the linear theory, we introduce a first type of nonlinear problem that has today invaded the whole mathematical world: variational inequalities. In particular, in Chapter 6, we introduce a simple theory of regularity for nonlocal variational inequalities. We also attack the question of the existence, uniqueness and approximation of solutions of quasilinear and mono tone problems (see Chapters 5, 7, 8). The material needed to read these parts is contained in Chapter 2. The arguments are explained using the simplest possible examples.
Ausgehend vom Schulstoff, der kurz wiederholt wird, führt der Autor in die Grundbegriffe der Mathematik ein, die von vielen naturwissenschaftlichen Disziplinen verwendet werden. Bei der Vertiefung des Inhaltes helfen eine Vielzahl von Abbildungen, Beispielen, Beweisen und interessanten Übungsaufgaben mit vielen ausführlichen Lösungen. Um die spezifische Denkart der Mathematik zu trainieren und den Studierenden die Furcht vor Beweisen zu nehmen, werden alle mathematischen Aussagen vollständig, aber mit großer Transparenz, erläutert.
