Geometric Group Theory Seminar - Shi Wang
Title: Homological norms on nonpositively curved manifolds
Speaker: Shi Wang (Indiana University Bloomington)
Abstract: Gromov norm is a topological invariant that measures how efficiently a homology class can be represented by the linear combinations of singular simplices. In this talk, we relate the Gromov norm on homology classes to the harmonic norm on the dual cohomology and obtain double sided bounds in terms of the volume and other geometric quantities of the underlying manifolds. This extends the previous result of Brock and Dunfield.
