Gassmann triples with special cycle types and applications
Holger Kammeyer, Steffen Kionke
We show that if one of various cycle types occurs in the permutation action of a finite group on the cosets of a given subgroup, then every almost conjugate subgroup is conjugate.…
Steep uncountable groups
Samuel M. Corson, Alexander Olshanskii, Olga Varghese
We produce a simple group of cardinality which is Artinian (every strictly descending chain of subgroups is finite), satisfies a Burnside law and such that for each…
Bounded cohomology is not a profinite invariant
Daniel Echtler, Holger Kammeyer
We construct pairs of residually finite groups with isomorphic profinite completions such that one has non-vanishing and the other has vanishing real second bounded cohomology. The…
Common zeros of irreducible characters
Nguyen N. Hung, Alexander Moretó, Lucia Morotti
We study the zero-sharing behavior among irreducible characters of a finite group. For symmetric groups , it is proved that, with one exception, any two irreducible characters…
Finite axiomatizability of the rank and the dimension of a pro- group
Martina Conte, Benjamin Klopsch
The Prüfer rank of a profinite group is the supremum, across all open subgroups of , of the minimal number of generators . It is known th…
Strong conciseness of coprime commutators in profinite groups
Iker de las Heras, Matteo Pintonello, Pavel Shumyatsky
Let be a profinite group. The coprime commutators and are defined as follows. Every element of is both a -value and a -value. For , l…
