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.

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.

This is not a typical math textbook, it does not present full developments of key theorems, but it leaves strategic gaps in the text for the reader to fill in. The original text underlying this book was a set of notes for the Math Olympiad Program.
