Closed frame homomorphisms

open access: yes, 1991
This thesis is a systematic study of closed frame homomorphisms, which can be viewed as a natural generalization of the classical closed continuous mappings of topological spaces.

Homomorphisms of quantum hypergraphs

open access: yes, 2023
We introduce quantum homomorphisms between quantum hypergraphs through the existence of perfect strategies for quantum non-local games, canonically associated with the quantum hypergraphs.

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

open access: yesCategories 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.

Binary homomorphisms and natural dualities

open access: yes, 2002
We investigate ways in which certain binary homomorphisms of a finite algebra can guarantee its dualisability. Of particular interest are those binary homomorphisms which are lattice, flat-semilattice or group operations.

Generalized left derivations acting as homomorphisms and anti-homomorphisms on Lie ideal of rings

open access: yes, 2014
Let R be a prime ring with characteristic different from 2 and L be a Lie ideal of R. In this paper, we characterize generalized left derivation, which acts as a homomorphisms or an anti-homomorphisms on ...

Stability of n-Lie homomorphisms and Jordan n-Lie homomorphisms on n-Lie algebras

open access: yes, 2013
The motivation of this paper is to apply the Hypers-Ulam stability problems of some kinds of functional equations to the classes of n-Lie homomorphisms and n-Lie algebras by using the structures of n-Lie homomorphisms and n-Lie algebras.

Homomorphisms preserving types of density [PDF]

open access: yes, 2009
The concept of density in a free monoid can be generalized from the infix relation to arbitrary relations. Many of the properties known for density can be established over these more general notions of densities.
