Let (X, g) be a metrically complete, simply connected Riemannian manifold with bounded geometry and pinched negative curvature, i.e. there are constants a > b > 0 such that −a < K < −b for all sectional curvatures K. Here bounded geometry is used in the sense of Shubin, [7, Appendix 1], namely that all covariant derivatives of the Riemannian curvature… CONTINUE READING
