This modern translation of Sophus Lie's and Friedrich Engel's "Theorie
der Transformationsgruppen I" will allow readers to discover the
striking conceptual clarity and remarkably systematic organizational
thought of the original German text. Volume I presents a comprehensive
introduction to the theory and is mainly directed towards the
generalization of ideas drawn from the study of examples. The major part
of the present volume offers an extremely clear translation of the lucid
original. The first four chapters provide not only a translation, but
also a contemporary approach, which will help present day readers to
familiarize themselves with the concepts at the heart of the subject.
The editor's main objective was to encourage a renewed interest in the
detailed classification of Lie algebras in dimensions 1, 2 and 3, and to
offer access to Sophus Lie's monumental Galois theory of continuous
transformation groups, established at the end of the 19th Century. Lie
groups are widespread in mathematics, playing a role in representation
theory, algebraic geometry, Galois theory, the theory of partial
differential equations and also in physics, for example in general
relativity. This volume is of interest to researchers in Lie theory and
exterior differential systems and also to historians of mathematics. The
prerequisites are a basic knowledge of differential calculus, ordinary
differential equations and differential geometry.
