Cohomological obstructions to local-global principles - lecture 4

By Cyril Demarche

Also appears in collection : Research School

Hasse proved that for quadrics the existence of rational points reduces to the existence of solutions over local fields. In many cases, cohomological constructions provide obstructions to such a local to global principle. The objective of these lectures is to give an introduction to these cohomological tools.
