Conjugator length in finitely generated groups

G. Goffer, M. Mihaila, D. Osin

We describe all functions that can be realized, up to the standard equivalence, as conjugator length functions of finitely generated groups. Furt…

Compact Invariant Random Subgroups

Tal Cohen, Helge Glöckner, Gil Goffer +1

We study ergodic invariant random subgroups that give full measure to the subset of compact subgroups. We show that in real Lie groups, compactly generated -adic Lie groups, loc…

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…

Frattini subgroups of hyperbolic-like groups

Gil Goffer, Denis Osin, Ekaterina Rybak

We study Frattini subgroups of various generalizations of hyperbolic groups. For any countable group admitting a general type action on a hyperbolic space , we show that the…

A note on the Zariski topology on groups

Gil Goffer, Be'eri Greenfeld

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…

Probabilistic Burnside groups

Gil Goffer, Be'eri Greenfeld

We prove that there exists a finitely generated group that satisfies a group law with probability 1 but does not satisfy any group law. More precisely, we construct a finitely gene…

Invariable generation does not pass to finite index subgroups

Gil Goffer, Nir Lazarovich

Using small cancellation methods, we show that the property invariable generation does not pass to finite index subgroups, answering questions of Wiegold and Kantor-Lubotzky-Shalev…

A few remarks on invariable generation in infinite groups

Gil Goffer, Gennady A. Noskov

A subset of a group invariably generates if is generated by for any choice of . In case is topological one defines si…
