The speed of random walks on semigroups
Guy Blachar, Be'eri Greenfeld
We construct, for each real number , a random walk on a finitely generated semigroup whose speed exponent is . We further show that the speed function of a random…

Asymptotic Burnside laws
Gil Goffer, Be'eri Greenfeld, Alexander Yu. Olshanskii
We construct novel examples of finitely generated groups that exhibit seemingly-contradicting probabilistic behaviors with respect to Burnside laws. We construct a finitely generat…

We show that the semigroup Zariski topology on a group can be strictly coarser than the group Zariski topology on it, answering a question of Elliott, Jonusas, Mesyan, Mitchell, Mo…
