Boundedly finite conjugacy classes of tensors [PDF]
Let $n$ be a positive integer and let $G$ be a group. We denote by $\nu(G)$ a certain extension of the non-abelian tensor square $G \otimes G$ by $G \times G$. Set $T_{\otimes}(G) = \{g \otimes h \mid g,h \in G\}$.

On a result of nilpotent subgroups of solvable groups [PDF]
Heineken [H. Heineken, Nilpotent subgroups of finite soluble groups, Arch. Math.(Basel), 56 no. 5 (1991) 417--423.] studied the order of the nilpotent subgroups of the largest order of a solvable group.

A probabilistic version of a theorem of lászló kovács and hyo-seob sim [PDF]
For a finite group group, denote by $\mathcal V(G)$ the smallest positive integer $k$ with the property that the probability of generating $G$ by $k$ randomly chosen elements is at least $1/e.$ Let $G$ be a finite soluble group.

On the probability of zero divisor elements in group rings [PDF]
Let $R$ be a non trivial finite commutative ring with identity and $G$ be a non trivial group. We denote by $P(RG)$ the probability that the product of two randomly chosen elements of a finite group ring $RG$ is zero. We show that $P(RG)

Some results on the join graph of finite groups [PDF]
Let $G$ be a finite group which is not cyclic of prime power order. The join graph $\Delta(G)$ of $G$ is a graph whose vertex set is the set of all proper subgroups of $G$, which are not contained in the Frattini subgroup $G$ and two distinct ...

The minimum sum of element orders of finite groups [PDF]
Let $ G $ be a finite group and \( \psi(G)=\sum_{g\in G}o(g) \), where $ o(g) $ denotes the order of $g\in G$. We show that the Conjecture 4.6.5 posed in [Group Theory and Computation, (2018) 59-90], is incorrect.

A presentation for the subgroup of compressed conjugating automorphisms of a partially commutative group [PDF]
Let $G_{Gamma}$ be a partially commutative group. We find a finite presentation for the subgroup $Conjv(G_{Gamma})$ of compressed vertex conjugating automorphisms of the automorphism group $Aut(G_{Gamma})$ of $G_{G}$.

On almost recognizability by spectrum of simple classical groups [PDF]
The set of element orders of a finite group $G$ is called the {em spectrum}. Groups with coinciding spectra are said to be {em isospectral}. It is known that if $G$ has a nontrivial normal soluble subgroup then there exist infinitely many pairwise ...

The number of maximal subgroups and probabilistic generation of finite groups [PDF]
In this survey we present some significant bounds for the number of maximal subgroups of a given index of a finite group. As a consequence, new bounds for the number of random generators needed to generate a finite $d$-generated group with high

An extension and a generalization of Dedekind's theorem [PDF]
For any given finite abelian group, we give factorizations of the group determinant in the group algebra of any subgroups. The factorizations is an extension of Dedekind's theorem. The extension leads to a generalization of Dedekind's theorem.
