We study the uniformly recurrent subgroups of simple locally finite groups.
We classify the sequences Sn | n ∈ N of finite simple nonabelian groups such that n Sn has uncountable cofinality.
Let G be a connected semisimple Lie group with at least one absolutely simple factor S such that R-rank(S) ≥ 2 and let Γ be a uniform lattice in G. (a) If CH holds, then Γ has a unique asymptotic… (More)
We present some applications of Popa’s Superrigidity Theorem to the theory of countable Borel equivalence relations. In particular, we show that the universal countable Borel equivalence relation E∞… (More)
A search motivated by supersymmetric models with light top squarks is presented using proton-proton collision data recorded with the CMS detector at a center-of-mass energy of ffiffi s p 1⁄4 7 TeV… (More)
We classify the ergodic invariant random subgroups of strictly diagonal limits of finite symmetric groups.
Throughout this paper Q will denote an infinite set, S:= Sym(Q) and G is a subgroup of S. If n: = |Q|, the cardinal of Q, then |.S| = 2". Working in ZFC, set theory with Axiom of Choice (AC), we… (More)
Under the assumption of Martin’s Conjecture, we prove a strong ergodicity result for the Turing equivalence relation ≡T .
