Introduction to Étale Cohomology

Etale Cohomology is one of the most important methods in modern Algebraic Geometry and Number Theory. Over the last few decades it has given fundamentally new insights into problems in arithmetic and algebraic geometry, leading to many applications and new results. The book gives a short and easy introduction to the world of Abelian Categories, Derived Functors, Grothendieck Topologies, Sheaves, General Etale Cohomology and Etale Cohomology of Curves.
