If you have a question about this talk, please contact Dr. J Ross.

In the first part of the talk, we propose and illustrate a refinement of Deligne’s principle: every infinitesimal deformation problem over a field of characteristic zero with cohomology constraints is governed by a differential graded Lie algebra together with a DGL -module. In the second part, we review recent results about the global structure of cohomology jump loci of rank one local systems. All this is joint work with Botong Wang.

This talk is part of the Algebraic Geometry Seminar series.
