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…
The Baer-invariant of a Semidirect Product
Behrooz Mashayekhy
In 1972 K.I.Tahara [7,2 Theorem 2.2.5], using cohomological method, showed that if a finite group is the semidirect product of a normal subgroup and a subgroup ,…
Higher Schur-multiplicator of a Finite Abelian Group
Mohammad Reza Rajabzadeh Moghaddam, Behrooz Mashayekhy
In this paper we obtain an explicit formula for the higher Schur-multiplicator of an arbitrary finite abelian group with respect to the variety of nilpotent groups of class at most…
Subgroup Theorems for the Baer-invariant of Groups
Mohammad Reza Rajabzadeh Moghaddam, Behrooz Mashayekhy, Saeed Kayvanfar
M.R.Jones and J.Wiegold in [3] have shown that if is a finite group with a subgroup of finite index , then the -th power of Schur multiplier of , , is isom…
A Remark on Generalized Covering Groups
Behrooz Mashayekhy
Let be the variety of nilpotent groups of class at most and be the direct sum of two finite cyclic groups. It is shown that if the…
Some Notes on the Baer Invariant of a Nilpotent Product of Groups
Behrooz Mashayekhy
W.Haebich (Bull. Austral. Math. Soc., 7, 1972, 279-296) presented a formula for the Schur multiplier of a regular product of groups. In this paper first, it is shown that the Baer-…
