On tensor analogues of commuting automorphisms and central automorphisms
Fahimeh Mohammadzadeh, Hanieh Golmakani, Azam Hokmabadi +1
In this paper, we introduce the tensor analogues of commuting automorphisms and central automorphisms. Then we give several properties of such automorphisms and apply these new con…
On the Order of the Schur Multiplier of a Pair of Finite p-Groups II
Fahimeh Mohammadzadeh, Azam Hokmabadi, Behrooz Mashayekhy
Let be a finite -group and be a normal subgroup of , with and . A result of Ellis (1998) shows that the order of the Schur multiplier of such a p…
Polynilpotent Multipliers of some Nilpotent Products of Cyclic Groups II
Azam Hokmabadi, Behrooz Mashayekhy, Fahimeh Mohammadzadeh
This article is devoted to present an explicit formula for the th nilpotent multiplier of nilpotent products of some cyclic groups $G={\bf {Z}}\stackrel{n_1}{*}{\bf {Z}}\stackre…
Polynilpotent Multipliers of Some Nilpotent Products of Cyclic Groups
Azam Hokmabadi, Behrooz Mashayekhy, Fahimeh Mohammadzadeh
In this article, we present an explicit formula for the th nilpotent multiplier (the Baer invariant with respect to the variety of nilpotent groups of class at most ) o…
Some Inequalities for Nilpotent Multipliers of Finite Groups
Behrooz Mashayekhy, Fahimeh Mohammadzadeh, Azam Hokmabadi
In this paper we present some inequalities for the order, the exponent and the number of generators of the -nilpotent multiplier (the Baer invariant with respect to the variety…
