Some results on compact convergence semigroups defined by filters

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
In this paper the concept of convergence defined by filters is used and applied in the study of semigroups. Special emphasis is placed on compact convergence semigroups and their properties.

Complete Reducibility in Good Characteristic

open access: yes, 2016
Let $G$ be a simple algebraic group of exceptional type, over an algebraically closed field of characteristic $p \ge 0$. A closed subgroup $H$ of $G$ is called $G$-completely reducible ($G$-cr) if whenever $H$ is contained in a parabolic subgroup $P$ of $

Green’s relations for 2 × 2 matrices over linearly ordered abelian groups [PDF]

open access: yesProceedings of the Estonian Academy of Sciences
We consider semigroups of 2 × 2 matrices over linearly ordered abelian groups with respect to multiplication, which is defined similarly to tropical algebra. We study Green’s relations on such semigroups.

Theoretical Researches about u-Maximal Subgroups and Its Applications in Charactering IntuG

open access: yesJournal of Chemistry, 2019
Let G be a finite group and u be the class of all finite supersoluble groups. A supersoluble subgroup U of G is called u-maximal in G if for any supersoluble subgroup V of G containing U, V=U.

The conjugacy diameters of non-abelian finite p-groups with cyclic maximal subgroups

open access: yesAIMS Mathematics
Let $ G $ be a group. A subset $ S $ of $ G $ is said to normally generate $ G $ if $ G $ is the normal closure of $ S $ in $ G. $ In this case, any element of $ G $ can be written as a product of conjugates of elements of $ S $ and their inverses.
