George R. Kempf

Complex Abelian Varieties and Theta Functions (eBook, PDF)

• Format: PDF

Produktbeschreibung

This book is distinguished from previous books on abelian varieties by its emphasis on analytic methods of geometry. Abelian varieties have been an active field within algebraic geometry and number theory, particularly during the last decade. Written for advanced students and researchers, Kempf's book is at a slightly higher level than other Universitext volumes.
