The Bogomolov multiplier of Lie superalgebras
Z. Araghi Rostami, P. Niroomand, M. Parviz
In this paper, we extend the notion of the Bogomolov multiplier and the commutativity preserving extension to Lie superalgebras. Moreover, we compute the Bogomolov multiplier of He…

On the values of commutativity degree of Lie algebras
Afsaneh Shamsaki, Ahmad Erfanian, Mohsen Parvizi
In this paper, the possible values of commutativity degree of Lie algebras are determined. Also, we define the asymptotic commutativity degree of Lie algebras and obtain the asympt…

On the commutativity degree of a finite-dimensional Lie algebra
Afsaneh Shamsaki, Ahmad Erfanian, Mohsen Parvizi
In this paper, we introduce the commutativity degree of a finite-dimensional Lie algebra over a finite field and determine upper and lower bounds for it. Moreover, we study some re…
