Abstract:
Given a topological space, the Gromov norm is a semi-norm defined on any singular homology class which measures how efficiently the class can be represented by the linear combinations of singular simplices. In many cases, this topological invariant is closely related to the geometry of the space. In this talk, I will present some of my recent work which focuses on closed manifolds of nonpositive sectional curvature.
