Location:

MPIM Lecture Hall [2]

Parent event:

Opening Conference for the Program on Higher Structures in Geometry and Physics [3]

(joint work with E. Aldrovandi) This talk will discuss a
basic question about cup products of cohomology classes of degree
one and relate it to the Heisenberg group. We will see how this
provides higher categorical invariants of codimension two algebraic
cycles.
