This course is the continuation of "Advanced topics in Algebra A".
The theory of étale cohomology is given the important tools to number theory, arithmetic geometry, representation theory, etc. In this course, we give an introduction to the theory of étale cohomology. We discuss the sheaf theory on Grothendieck topology, and explain the definition and properties of étale cohomology.
The goal of this course is to understand:
(1) the definition of étale cohomology,
(2) the relationship between étale cohomologies, Galois cohomologies and Zariski cohomologies,
(3) how to calculate low-dimensional étale cohomologies
Grothendieck topology, Zariski cohomology, étale cohomology
