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.

Homomorphic and restricted homomorphic products of soft graphs

Journal of the Nigerian Society of Physical Sciences
Molodtsov pioneered the notion of soft set theory, presenting it as a mathematical tool for dealing with uncertainty. Numerous researchers have subsequently developed models leveraging this theory to tackle challenges in decision-making and medical diagnosis.

Homomorphic relation on hyperingoinds and join hyperrings

Ratio Mathematica, 1999
This paper is a study of the Join Hyperringoid, which is a hypercompositional structure that has appeared recently. Here appear the homomorphic relations and a special type of such relations, the congruence ones.

On n-Derivations and n-Homomorphisms in Perfect Lie Superalgebras

Mathematics
Let n≥2 be a fixed integer. The aim of this paper is to investigate the properties of n-derivations within the framework of perfect Lie superalgebras over a commutative ring R. The main result shows that if the base ring contains 1n−1, and L is a perfect

Reflexive Homomorphic Relations [PDF]

Canadian Mathematical Bulletin, 1960
It is well known that a symmetric and transitive relation on a set is reflexive wherever it is defined. In this note we show that a converse is true for homomorphic relations in certain classes of algebras.Consider a class of similar algebras which contains the sub-algebras and quotient algebras of each of its members.

An equivalence functor between local vector lattices and vector lattices [PDF]

Categories and General Algebraic Structures with Applications, 2018
We call a local vector lattice any vector lattice with a distinguished positive strong unit and having exactly one maximal ideal (its radical). We provide a short study of local vector lattices.
