Rigidity and equidistribution of random walks by diffeomorphisms near the conservative regime

Timothée Bénard, Zhiyuan Zhang

We consider a random walk on a closed manifold driven by a probability measure on the space of diffeomorphisms. Provided has compact support, satisfies certain ga…

Ergodicity of (co)expanding on average random dynamical systems

Jonathan DeWitt, Dmitry Dolgopyat, Zhiyuan Zhang

We prove ergodicity for random dynamics satisfying some expansion and irreducibility conditions. As a particular application, we show that if , $d\ge 2…

Spectral conditions for forbidden subgraphs in bipartite graphs

Yuan Ren, Jing Zhang, Zhiyuan Zhang

A graph is -free, if it contains no as a subgraph. A graph is said to be \emph{-minor free}, if it does not contain as a minor. In recent years, Nikiforov asked t…

Geometric properties of partially hyperbolic measures and applications to measure rigidity

Alex Eskin, Rafael Potrie, Zhiyuan Zhang

We give a geometric characterization of the quantitative non-integrability, introduced by Katz, of strong stable and unstable bundles of partially hyperbolic measures and sets in d…

On pseudo-rotations of the annulus with generic rotation number

Barney Bramham, Zhiyuan Zhang

We show that for a Baire generic rotation number , the set of area preserving -pseudo-rotations of the annulus with rotation nu…

On bifurcation of statistical properties of partially hyperbolic endomorphisms

Masato Tsujii, Zhiyuan Zhang

We give an example of a path-wise connected open set of partially hyperbolic endomorphisms on the -torus, on which the SRB measure exists for each system and varies s…
