Buch. Condizione: Neu. Neuware -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.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 268 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Dieses Buch beschreibt die lange Reise eines Forschers ins Land der Entwicklungs biologie. Sie beginnt mit eigenartigen winzigen Taufliegen, die Beine statt Fühler aufdem Kopftragen, und führt über die Isolation des betreffenden Gens, das infol ge einer Mutation die Umwandlung von Fühlern in Beine hervorbringt, bis zur Entdeckung der Homeobox, einem kleinen Abschnitt der Erbsubstanz DNA. Die ses kleine Stück DNA ist charakteristisch für homeotische Gene, die den Bauplan, die Architektur der Taufliege und allen höheren Organismen, einschließlich des Menschen, bestimmen. Die Homeobox liefert einen Schlüssel zum Verständnis der Entwicklungsvorgänge, die vom befruchteten Ei bis zum erwachsenen Organismus führen. Die Homeobox enthält in verschlüsselter Form die Information zur Syn these der Homeodomäne, die nach dem genetischen Code aus der Sprache der Erbsubstanz in die Sprache der Proteine übersetzt wird. Die Reise führt uns von den Antennenbeinen am Kopf der Taufliege Drosophila bis hinunter zu den mole kularen Grundlagen, der atomaren Struktur der Homeodomäne. Im zweiten Teil der Reise befassen wir uns mit Problemen der Evolution, fragen nach dem histori schen Ursprung der homeotischen Gene und der Baupläne der Tiere. Die Entdek kung des Master-Kontrollgens, das für die Entwicklung der Augen verantwortlich ist, wirft ein neues Licht auf die Evolution der verschiedenen Augentypen, einem alten Rätsel der Evolutionsbiologie. Natürlich war der Weg dieser wissenschaftlichen Entdeckungsreise nicht so geradlinig, wie er in diesem Buch nachgezeichnet ist, sondern mit vielen Abzwei gungen versehen, die entweder in die falsche Richtung oder in Sackgassen führten.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 296 pp. Deutsch.
