The Structure of Almost Stationary Measures

Ilya Gekhtman, Simon Machado, Omri Solan +1

Let $G$ be a higher-rank simple Lie group acting on a space $X$ . A theorem of Nevo and Zimmer asserts that every ergodic stationary probability measure on $X$ is either $G$ -invaria…

Applications of Almost Stationarity I: Quantitative Growth of Injectivity Radius and StÃ¼ck-Zimmer Theorem

Ilya Gekhtman, Simon Machado, Omri Solan +1

Fraczyk and Gelander proved in \cite{FG} that for any simple Lie group $G$ of high rank and for every non-lattice discrete subgroup $I^ \leq G$ , the injectivity radius of points in…

Directional $p$ -Adic Littlewood Conjecture for Algebraic Vectors

Yuval Yifrach

For every vector $\overline Î±\in \RR^n$ and for every rational approximation $(\overline p,q)\in \RR^n\times\RR$ we can associate the displacement vector $q I^\pm - p$ . We foc…

Tori Approximation of Families of Diagonally Invariant Measures

Omri Nisan Solan, Yuval Yifrach

We approximate any portion of any orbit of the full diagonal group $A$ in the space of unimodular lattices in $\RR^n$ using a fixed proportion of a compact $A$ -orbit. Using those a…
