Hindman's finite sums theorem and its application to topologizations of algebras

open access: yes, 2018
The first part of the paper is a brief overview of Hindman's finite sums theorem, its prehistory and a few of its further generalizations, and a modern technique used in proving these and similar results, which is based on idempotent ultrafilters in ...

Spheres over fields, their entire rational maps and applications

open access: yesPracì Mìžnarodnogo Geometričnogo Centru
The paper summarizes some results on algebraic geometry presence in the homotopy theory. For the homotopy group πm(Sn), denote by πalgm(Sn) its subset of homotopy classes represented by ℝ-entire rational maps Sm→Sn of spheres.

Stone and Flat Topologies on the Minimal Prime Spectrum of a Commutator Lattice

open access: yesAxioms
In previous work we have studied minimal prime spectra, as well as extensions of universal algebras whose term condition commutator behaves like the modular commutator in the sense that it is commutative and distributive with respect to arbitrary joins ...

Congruence Extensions in Congruence–Modular Varieties

open access: yesAxioms
We investigate from an algebraic and topological point of view the minimal prime spectrum of a universal algebra, considering the prime congruences with respect to the term condition commutator.

On prime spaces of neutrosophic extended triplet groups

open access: yesOpen Mathematics
This article aims to investigate the Zariski topology on the set of prime ideals of a weak commutative neutrosophic extended triplet group (NETG) NN, denoted by Prim(N){\rm{Prim}}\left(N).

The topology of the generic polar curve and the Zariski invariant for branches of genus one

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
We study, for plane complex branches of genus one, the topological type of its generic polar curve, as a function of the semigroup of values and the Zariski invariant of the branch.
