[1910.05822] Cheeger-Gromoll Splitting Theorem for groups
Oct 13, 2019 · We study a notion of curvature for finitely generated groups which serves as a role of Ricci curvature for Riemannian manifolds. We prove an analog of Cheeger-Gromoll splitting theorem. As a consequence, we give a geometric characterization of virtually abelian groups.
We show there exists a closed locally symmetric manifold M modeled on SLn(R)/ SO ( ), n and a non-trivial homology class in degree dim (M ) rank (M ) represented by a totally geodesic submanifold that contains a circle factor. As a result, the comparison map ck : Hk b (M , R) → Hk (M , is not surjective in degree k. R) dim = (M ) − rank (M ).

Abstract: For a complete Riemannian manifold of nonpositive curvature, we introduce a flow. We give an upper bound on the k-Jacobian of the flow in terms of the critical exponent of the fundamental group.

Mar 15, 2016 · Speaker: Shi Wang (OSU) Abstract: In this talk, I will report on joint work with Jean Lafont. We show that, for an $n$-dimensional irreducible symmetric space of rank $r\geq 2$ (excluding $SL(3,\mathbb R)/SO(3)$ and $SL(4, \mathbb R)/SO(4)$), the $p$-Jacobian of barycentrically straightened simplices has uniformly bounded norm, provided $p\geq ...
