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.
