Pinching estimates for negatively curved manifolds with nilpotent fundamental groups
Igor Belegradek, Vitali Kapovitch
Let be a complete Riemannian metric of sectional curvature within whose fundamental group contains a -step nilpotent subgroup of finite index. We prove that $a\g…

Classification of negatively pinched manifolds with amenable fundamental groups
Igor Belegradek, Vitali Kapovitch
We give a diffeomorphism classification of pinched negatively curved manifolds with amenable fundamental groups, namely, they are precisely the Möbius band, and the products of a l…
