The next meeting of the Reading Seminar in Algebraic Geometry will be held on December 11, 2014 (Thursday) at 16:00 in Room 503 of IMI.

A talk on:

Examples of 0- and 1- connections. Dixmier-Douady classes

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

Everybody is invited.

Abstract.
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.
