On the dimension of the Schur Lie-multiplier of a pair of Leibniz algebras

H Safa - Journal of Algebra, 2021 - Elsevier
Let 0→ r→ f→ q→ 0 be a free presentation of a Leibniz algebra q and m≅ s/r be a two-sided
ideal of q such that s is a two-sided ideal of f. In this paper, we study the notion of the Schur …

The Schur multiplier of an n-Lie superalgebra

H Safa - Communications in Algebra, 2022 - Taylor & Francis
In the present paper, we study the notion of the Schur multiplier M (L) of an n-Lie
superalgebra L= L 0⊕ L 1 and prove that dim M (L)≤∑ i= 0 n (mi) L (n− i, k), where dim L …

Some Results on c-Covers of A Pair of Groups

H Arabyani - Global Analysis and Discrete Mathematics, 2022 - gadm.du.ac.ir
Let G be a group and N be a normal subgroup of G. In this paper, we provide some results
on c-covers of a pair of groups. Moreover, we prove that every c-perfect pair of groups (G, N) …
