What is a “nonlinear” near-symplectic form?

Dylan Galt, Harvard

What is a “nonlinear” near-symplectic form? (60 minutes) In this talk, I will explain how one might understand this question and why a possible answer can be found in the geometry of coassociative 4-folds, a special class of minimal submanifolds discovered by Harvey and Lawson.

Cohomology of configuration space of points (30 minutes) Configuration space of points is an interesting and important subject in mathematics and physics. I’ll review some classical results computing cohomology of configuration space of points. I’ll also introduce some recent progress in computing sheaf cohomology of configuration space of affine space.
