Algebraic Geometry

Location:  4096 East Hall (4:10 PM to 5:30 PM)

Title:  Canonical paths and monodromy

Abstract:   Let K be a local field (archimedean or non-archimedean) and X a normal variety over X. Then, in several settings, there exist canonical linear combinations of paths between any two points in X. I'll explain several applications of this observation: (1) a monodromy-free theory of iterated integration on complex varieties, (2) some structural results about Galois actions on pro-\ell geometric fundamental groups of varieties over p-adic local fields, for p different from \ell, and (3) results on the representation theory of arithmetic fundamental groups.
