Profinite rigidity of affine Coxeter groups
Samuel M. Corson, Sam Hughes, Philip Möller +1
We prove that affine Coxeter groups are profinitely rigid.
Involutions in Coxeter groups
Anna Michael, Yuri Santos Rego, Petra Schwer +1
We combinatorially characterize the number of conjugacy classes of involutions in any Coxeter group in terms of higher rank odd graphs. This notion naturally genera…
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…
