On Frobenius graphs of diameter 3 for finite groups
Thomas Breuer, László Héthelyi, Erzsébet Horváth +1
For a subgroup of a finite group , the Frobenius graph records the constituents of the restrictions to of the irreducible characters of . We investigate whe…
The Loewy Structure of Certain Fixpoint Algebras, Part II
Thomas Breuer, László Héthelyi, Erzsébet Horváth +1
In Part I of this paper, we introduced a class of certain algebras of finite dimension over a field. All these algebras are split, symmetric and local. Here we continue to investig…
The depth of the maximal subgroups of Ree groups
László Héthelyi, Erzsébet Horváth, Franciska Petényi
We determine the combinatorial and the ordinary depth of the maximal subgroups of the simple Ree groups, .
The Maschke property for the Sylow p-subgroups of the symmetric group S_p^n
David J. Green, László Héthelyi, Erzsébet Horváth
The Sylow p-subgroups of the symmetric group S_p^n satisfy the appropriate generalization of Maschke's Theorem to the case of a p'-group acting on a (not necessarily abelian) p-gro…
