Research Project: In this project, flows on manifolds that are very weakly hyperbolic or not hyperbolic at all are the central topic. Examples are horocycle flows on surfaces of negative curvature and polygonal billiards such as Ehrenfest's wind-tree model. We are interested in whether various stochastic (spatial and temporal) limit laws hold or fail, and in the corresponding scaling sequences (and diffusion rates, if applicable).
