In this paper: For every n-dimensional nilpotent Lie algebra L, let ℳ(L)be the Schur multiplier of L. Then we define t(L) by t(L) = 1/2(n2 – n) – dimℳ(L). We classify nilpotent Lie algebras L satisfying t(L) = 13.

In this paper: For a finite group G, we introduce the concept of commutativity degree of its cyclic chains. We denote the commutativity degree of cyclic chains of a group G by ccd(G), and compute this measure for so...

In this paper: The concepts of commutativity of two chains, and the commutativity degree of the chains of a finite group such as G which ends in G are introduced. Then, the relation between the commutativity degree...
