Finite groups with non-trivial intersections of kernels of all but one irreducible characters
(University of Isfahan, 2018-09-01)In this paper we consider finite groups $G$ satisfying the following condition: $G$ has two columns in its character table which differ by exactly one entry. It turns out that such groups exist and they are exactly ...

Fragile words and Cayley type transducers
(University of Isfahan, 2018-09-01)We address the problem of finding examples of non-bireversible transducers defining free groups, we show examples of transducers with sink accessible from every state which generate free groups, and, in general, we link ...

Groups with permutability conditions for subgroups of infinite rank
(University of Isfahan, 2018-09-01)In this paper, the structure of non-periodic generalized radical groups of infinite rank whose subgroups of infinite rank satisfy a suitable permutability condition is investigated.

Inertial properties in groups
(University of Isfahan, 2018-09-01)Let $G$ be a group and $p$ be an endomorphism of $G$. A subgroup $H$ of $G$ is called $p$-inert if $H^pcap H$ has finite index in the image $H^p$. The subgroups that are $p$-inert for all inner ...

On nonsolvable groups whose prime degree graphs have four vertices and one triangle
(University of Isfahan, 2018-09-01)Let $G$ be a finite group. The prime degree graph of $G$, denoted by $Delta(G)$, is an undirected graph whose vertex set is $rho(G)$ and there is an edge between two distinct primes $p$ and $q$ if and only if ...
