On the pair of nilpotent Lie algebras

Mostafa Sajedi, Mohammad Reza R. Moghaddam

Let $(N, L)$ be a pair of finite dimensional nilpotent Lie algebras and $N$ admits a complement $K$ in $L$ such that $dim N = n$ and $dim K = m$ . Let $s(N,L)=\frac{1}{2}(n-1)(n-2)+1+(…

The Higher Schur-Multiplicator of Certain Classes of Groups

M. R. R. Moghaddam, B. Mashayekhy, S. Kayvanfar

The paper is devoted to calculating the higher Schur-multiplicator of certain classes of groups with respect to the variety of nilpotent groups. Our results somehow generalize the…

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 $G$ is a finite group with a subgroup $H$ of finite index $n$ , then the $n$ -th power of Schur multiplier of $G$ , $M (G)^{n}$ , is isom…

On Izumi's theorem on comparison of valuations

Mohammad Moghaddam

We prove that the sequence of MacLane key polynomials constructed in \cite{Mac1} and \cite{Sp2} for a valuation extension $(K, ν) \subset (K (x), μ)$ is finite, provided that both $ν$ …

Realization of a certain class of semi-groups as value semi-groups of valuations

M. Moghaddam

Given a well-ordered semi-group $Γ$ with a minimal system of generators of ordinal type at most $ω n$ and of rational rank $r$ , which satisfies a positivity and increasing condition…
