In this paper: In this paper, we classify all n-dimensional generalized Heisenberg Lie algebras of rank (n – 4), and to this end, we demonstrate that for any n-dimensional generalized Heisenberg Lie algebra, if the...

In this paper: We investigate the minimum enclosing ball problem for given n points in fixed dimension d. We present three new approximation algorithms to the problem: a√d-approximation algorithm, a 2-approximation...

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...
