| Research Abstract |
Hyperbolic group was invented by Gromov in 80's. We aim to use hyperbolicity in broader objects. We constructed many quasi-homomorphisms on Kac-Moody groups. We obtained a first finitely presented, simple group with infinite commutator width (with Caprace). Using quasi-homomorphisms, we characterized rank-1 manifolds among complete Riemann manifold of non-positive curvature of finite volume (with Bestvina).
