Elementary Lie Group Analysis and Ordinary Differential Equations

Die Erkenntnis, daß sich die bekannten Methoden der Integration gewöhnlicher Differentialgleichungen mit Hilfe der Gruppentheorie vereinigen und herleiten lassen, verdanken wir Marius Sophus Lie. Bis heute wurden die Möglichkeiten der Lie-Gruppen-Analysis nicht vollständig erschlossen - der Autor dieses vornehmlich für fortgeschrittene Studenten und Lehrende gedachten Buches versucht mit zahlreichen theoretischen und anwendungsbezogenen Beispielen zur Schließung dieser Lücke beizutragen.(05/99),Lie group analysis, based on symmetry and invariance principles, is the only systematic method for solving nonlinear differential equations analytically. One of Lie‘s striking achievements was the discovery that the majority of classical devices for integration of special types of ordinary differential equations could be explained and deduced by his theory. Moreover, this theory provides a universal tool for tackling considerable numbers of differential equations when other means of integration fail. * This is the first modern text on ordinary differential equations where the basic integration methods are derived from Lie group theory * Includes a concise and self contained introduction to differential equations * Easy to follow and comprehensive introduction to Lie group analysis * The methods described in this book have many applications The author provides students and their teachers with a flexible text for undergraduate and postgraduate courses, spanning a variety of topics from the basic theory through to its many applications. The philosophy of Lie groups has become an essential part of the mathematical culture for anyone investigating mathematical models of physical, engineering and natural problems.
