Pushforward dynamics on Wasserstein spaces and measure rigidity

Douglas Finamore, André Magalhães de Sá Gomes, Christian S. Rodrigues

For an endomorphism $ϕ$ of a closed Riemannian manifold $M$ , we study the pushforward action $ϕ_{*}$ on the Wasserstein space $P (M)$ at a measure $μ_{0}$ preserved by $ϕ$ .…

A CAT(0)-approach to the marked length spectral rigidity of Sinai billiards

Douglas Finamore, Martin Leguil

We study the spectral rigidity problem for Sinai billiards with finite horizon, specifically asking whether the geometry of the billiard table can be recovered from the lengths of…

Quasiconformal contact foliations

Douglas Finamore

We show that every quasiconformal contact foliation supports an invariant metric and characterise such foliations by the dynamical property of $C^{1}$ -equicontinuity. We prove that a…
