Generalized Lower and Upper Approximations in Quantales

Journal of Applied Mathematics, 2012
We introduce the concepts of set-valued homomorphism and strong set-valued homomorphism of a quantale which are the extended notions of congruence and complete congruence, respectively.

Lifting group homomorphisms [PDF]

Pacific Journal of Mathematics, 1983
If a knot K has Alexander polynomial different from 1, then its knot group, G maps onto some metacyclic group, Zr§Zp. We show that in that case, it also has a homomorphism onto a split extension of a free abelian group of rank p — 1 by Zr§Zp, and hence also onto a split extension of a direct sum of p — 1 cyclic groups of order s by the metacyclic group.

Degree-Constrained Steiner Problem in Graphs with Capacity Constraints

Mathematics
The degree-constrained Steiner problem in graphs is well known in the literature. In an undirected graph, positive integer degree bounds are associated with nodes and positive costs with the edges.

Ring homomorphisms on H(G)

International Journal of Mathematics and Mathematical Sciences, 1990
It is shown that a ring homomorphism on H(G), the algebra of analytic functions on a regular region G in the complex plane, is either linear or conjugate linear provided that the ring homomorphism takes the identity function into a nonconstant function.

A New Type of Weakly Commutative Groups

Science Journal of University of Zakho, 2017
The aim of the present paper is to define and study a new class of groups, namely Wm-groups with a single binary operation based on axioms of semi commutativity, right identity and left inverse.

A pointfree version of remainder preservation [PDF]

Categories and General Algebraic Structures with Applications, 2013
Recall that a continuous function $fcolon Xto Y$ between Tychonoff spaces is proper if and only if the Stone extension $f^{beta}colon beta Xtobeta Y$ takes remainder to remainder, in the sense that $f^{beta}[beta X-X]subseteq beta Y-Y$.

Q-soft Translation of Q-soft Subgroups

Journal of New Theory, 2020
In this study, we introduce the concept Q-soft translations of Q-soft subgroups. Next we investigate the properties of them and we prove that every Q-soft translation of Q-soft subgroup is also Q-soft subgroup.
