CH-groups which are finite $p$-groups
(University of Isfahan, 2012-12-01)In their paper "Finite groups whose noncentral commuting elements have centralizers of equal size", S. Dolfi, M. Herzog and E. Jabara classify the groups in question- which they call $ CH$-groups- up ...

Finite simple groups with number of zeros slightly greater than the number of nonlinear irreducible characters
(University of Isfahan, 2012-12-01)The aim of this paper is to classify the finite simple groups with the number of zeros at most seven greater than the number of nonlinear irreducible characters in the character tables. We find that they are exactly ...

On Graham Higman's famous PORC paper
(University of Isfahan, 2012-12-01)We investigate Graham Higman's paper Enumerating $p$-groups, II, in which he formulated his famous PORC conjecture. We are able to simplify some of the theory. In particular, Higman's paper ...
