Stationary Measures on Markov surfaces

By Serge Cantat

Also appears in collection : 2024 - T2 - WS2 - Group actions with hyperbolicity and measure rigidity

Markov surfaces are certain (non-compact) algebraic, cubic surfaces in the affine 3-space. There is a natural group acting on them by algebraic, polynomial transformations. I will study stationary probability measures for this group action. This is a joint work with Christophe Dupont and Florestan Martin-Baillon.
