Abstract

We give a new fractal Weyl upper bound for resonances of convex co-compact hyperbolic manifolds in terms of the dimension of the manifold and the dimension of its limit set. More precisely, we show that as , the number of resonances in the box is , where the exponent changes its behavior at . In the case , we also give an improved resolvent upper bound in the standard resonance free strip . Both results use the fractal uncertainty principle point of view recently introduced in [DyZa]. The appendix presents numerical evidence for the Weyl upper bound.
