Finite groups with large Noether number are almost cyclic
Pál Hegedűs, Attila Maróti, László Pyber
Noether, Fleischmann and Fogarty proved that if the characteristic of the underlying field does not divide the order of a finite group , then the polynomial invariants of…
Transposable character tables, dual groups
Ivan Andrus, Pál Hegedűs, Tetsuro Okuyama
One way of expressing the self-duality $A\cong \Hom(A,\mathbb{C})$ of Abelian groups is that their character tables are self-transpose (in a suitable ordering). Noncommutative grou…
Determination of Conjugacy Class Sizes from Products of Characters
Ivan Andrus, Pál Hegedűs
Robinson showed that the character degrees are determined by knowing, for all , the number of ways that the identity can be expressed as a product of commutators. Earlier, S…
On the number of generators needed for free profinite products of finite groups
Miklos Abert, Pal Hegedus
We provide lower estimates on the minimal number of generators of the profinite completion of free products of finite groups. In particular, we show that if C_1,...,C_n are finite…
