The next meeting of the Reading Seminar in Algebraic Geometry will be held on December 18, 2014 (Thursday) at 16:00 in Room 503 of IMI.

A talk on:

Examples of 0- and 1- connections. Dixmier-Douady classes (2)

will be delivered by Peter Dalakov, Institute of Mathematics and Informatics.

Everybody is invited.

Abstract.
Continuation from last week: We are going to discuss some examples of connections on gerbe data. Then we will introduce the Dixmier-Douady class of a gerbe datum (3-curvature), which is the analogue of Chern classes of line bundles.
