Title:听Growth of mod-p homology in higher rank lattices
Abstract:听
It is known since late 70s that in locally symmetric spaces of large injectivity radius, the k-th real Betti number divided by the volume is approximately equal to the k-th L2-Betti number. Is there an analogue of this fact for mod-p Betti numbers? This question is still very far from being solved, except for certain special families of locally symmetric spaces. In this talk I want to advertise a relatively new approach to study the growth of mod-p Betti numbers based on a quantitative description of minimal area representatives of mod-p homology classes.
This information can also be found on the . We hope to see you all there.
