In several cases, the assumptions made for calculations or definitions and proofs have to be extracted from the context. Nevertheless, the physicist may get a feeling for the importance of modern differential and algebraic topology for his field and will appreciate the though uncomplete but ...
The main goal is to describe Thurston's geometrisation of three-manifolds, proved by Perelman in 2002. The book is divided into three parts: the first is devoted to hyperbolic geometry, the second to surfaces, and the third to three-manifolds. It contains complete proofs of Mostow's ...
in the first of these I have confined myself to those matters concerning pure analysis. In the second book I have explained those thing which must be known from geometry, since analysis is ordinarily developed in such a way that its application to geometry is shown. In the first book, sinc...

The purpose of this section is to shed some light on the nature of thesenew proofs.Euclidean geometry is concerned with the “metric” properties of figures, that is those properties that can be measured: lengths of lines, sizes of angles, areas,etc. From a metric perspective Figure 102 ...
This book presents a readable and accessible introductory course in algebraic geometry, with most of the fundamental classical results presented with complete proofs. An emphasis is placed on developing connections between geometric and algebraic aspects of the theory. Differences between the theory in ch...
