241014 Local Cohomology (S) (WiSe 2014/2015)

Inhalt, Kommentar

Local cohomology was invented by Grothendieck in the early 1960s. Roughly speaking, it is a cohomology theory for sheaves on a topological space, which gives local information with respect to a closed subset (by taking the derived functors of sections). There are various versions of this theory and many applications depending on the context (algebra, geometry, topology).

The seminar provides an introduction to this beautiful theory, based to a large extent on the volume "Twenty-four hours of local cohomology".

Teilnahmevoraussetzungen, notwendige Vorkenntnisse

The participants of the seminar are supposed to be familiar with basic concept from (commutative and homological) algebra, including the language of rings and modules.
