A pointfree version of remainder preservation [PDF]
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 $f^{beta}[beta X-X]subseteq beta Y-Y$.

Abstract The notion of separoid homomorphisms was introduced in [Nesetřil, J., and R. Strausz, Universality of separoids, Arch. Math. (Brno) 42 (2006), 85–101], by Jarik Nesetřil and the author, where it was proved that separoids endowed with such maps constitute a dense and universal category.

Stability of ψ-additive mappings: applications to nonlinear analysis
The Hyers-Ulam stability of mappings is in development and several authors have remarked interesting applications of this theory to various mathematical problems.

Undecidability of polynomial inequalities in weighted graph homomorphism densities
Many problems and conjectures in extremal combinatorics concern polynomial inequalities between homomorphism densities of graphs where we allow edges to have real weights.

− In this paper, we introduce the concept of set-valued homomorphism of a lattice which isthe generalization of ordinary lattice homomorphism. We construct generalized rough lower and upperapproximations operators, by means of a set-valued mapping, which

Free Algebras of Full Terms Generated by Order-Preserving Transformations
Full terms, which serve as tools for classifying algebras into subclasses, can be studied using an algebraic approach. For a natural number n, this paper introduces the algebra of order-preserving full terms under the (n+1)-superposition operation ...

Fredholm Theory Relative to Any Algebra Homomorphisms
In this paper, we give another definition of Ruston elements and almost Ruston elements, which is equivalent to the definitions given by Mouton and Raubenheimer in the case that the homomorphism has a closed range and Riesz property.
