Asymptotic Cohomology and Uniform Stability for Lattices in Semisimple Groups
Lev Glebsky, Alexander Lubotzky, Nicolas Monod +1
It is, by now, classical that lattices in higher rank semisimple groups have various rigidity properties. In this work, we add another such rigidity property to the list: uniform s…
Property of defect diminishing and stability
Marco Antonio García Morales, Lev Glebsky
We show that the defect diminishing is equivalent to the stability with linear rate.
Extension of a residually finite group by a residually finite group is weakly sofic
Lev Glebsky
We show that residually finite by residually finite extensions are weakly sofic.
On the number of even roots of permutations
Lev Glebsky, Melany Licón, Luis Manuel Rivera
Let be a permutation on letters. We say that a permutation is an even (resp. odd) th root of if and is an even (resp. odd) permutation. In this artic…
What is a true spectra of a finite Fourier transform
Javier Diaz-Vargas, Lev Glebsky, Carlos Jacob Rubio-Barrios
In this paper we deal with a finite abelian group and the abstract Fourier transform ${\mathcal F}:{\mathbb C}^G\to {\mathbb C}^\hat{G}$. Then, we consider $\tilde{j}\circ {\ma…
Unrestricted wreath products and sofic groups
Goulnara Arzhantseva, Federico Berlai, Martin Finn-Sell +1
We show that the unrestricted wreath product of a sofic group by an amenable group is sofic. We use this result to present an alternative proof of the known fact that any group ext…
