Lectures on Torus Embeddings and Applications
by Tadao Oda
Publisher: Tata Institute of Fundamental Research 1978
Number of pages: 158
In recent years, the theory of torus embeddings has been finding many applications. The point of the theory lies in its ability of translating meaningful algebra-geometric and analytic phenomena into very simple statements about the combinatorics of cones in affine space over the reals.

The aim of these lecture notes is first to introduce the reader to the theory of D-modules in the analytical setting and also to make a link with the theory of deformation quantization (DQ for short) in the complex setting.

This book discusses two subjects of quite different nature: Construction methods for quotients of quasi-projective schemes by group actions or by equivalence relations and properties of direct images of certain sheaves under smooth morphisms.

The purpose of this text is to give an introduction to Grothendieck's theory of the fundamental group in algebraic geometry with the study of the fundamental group of an algebraic curve over an algebraically closed field of arbitrary characteristic.
