@article{Katok1989DifferentiabilityAA, title={Differentiability and analyticity of topological entropy for Anosov and geodesic flows}, author={Anatole Katok and Gerhard Knieper and Mark Pollicott and Howard Weiss}, journal={Inventiones mathematicae}, year={1989}, volume={98}, pages={581-597} }

SummaryIn this paper we investigate the regularity of the topological entropyhtop forCk perturbations of Anosov flows. We show that the topological entropy varies (almost) as smoothly as the perturbation. The results in this paper, along with several related results, have been announced in [KKPW].
