Applications of Almost Stationarity I: Quantitative Growth of Injectivity Radius and Stück-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 $Γ \leq G$ , the injectivity radius of points in $…

$ASL_{n} (Z)$ invariant random subsets of $Z^{n}$

Mikołaj Frączyk, Simon Machado

We classify measures on ${0, 1}^{Z^{d}}$ , $d \geq 3$ , the space of subsets of $Z^{d}$ , which are invariant under all affine special linear transformations. In other…

On the structure of approximate rings

Krzysztof Krupiński, Simon Machado

By a [ $K$ -]approximate subring of a ring we mean an additively symmetric subset $X$ such that $X \cdot X \cup (X + X)$ is covered by finitely many [resp.\ $K$ ] additive translates…
