Noncommutative Geometry and Cyclic Cohomology

Formal deformations of gerbes and etale groupoids.

3rd August 2006

Author: Alexancer Gorokhovsky (University of Colorado, Boulder)

Abstract

This is a joint work with P.Bressler, R. Nest and B. Tsygan. We give an explicit description of the differential graded Lie algebra which controls the deformation theory of gerbes and etale groupoids.
