DOI: 10.1007/s00012-019-0598-0
Abstract: A congruence is defined on a topological space. This leads to the topological versions of the algebraic isomorphism theorems and some of their consequences. In addition, a Hoehnke radical of a topological space is defined… read more here.

Abstract: What can we say about the properties of remainders of spaces which have a certain property $$\mathcal{P}$$ locally? Below, a rather general approach to this question is developed. In particular, we consider remainders of locally… read more here.

DOI: 10.1080/02331934.2019.1671384
Abstract: To the best of our knowledge, all the existing variational principles were established in the framework of a complete metric space or a Banach space. In this paper, we consider variational principles in topological spaces.… read more here.

Abstract: Abstract In this paper, we introduce a new way-below relation in T0 topological spaces based on cuts and give the concepts of SI2-continuous spaces and weakly irreducible topologies. It is proved that a space is… read more here.

Abstract: In this paper, we extend the notion of γ−operation by using the fuzzy soft ideal notions. Furthermore, we introduce some forms of fuzzy soft continuity in fuzzy soft topological spaces via fuzzy soft ideals. The… read more here.

DOI: 10.2989/16073606.2018.1516250
Abstract: Abstract We show that for certain quantales, the categories of quantale-valued gauge spaces and of quantale-valued approach system spaces are isomorphic to the category of quantale-valued bounded strong topological spaces. read more here.

DOI: 10.3390/axioms11020049
Abstract: The structure of topological spaces is analysed here through the lenses of fibrous preorders. Each topological space has an associated fibrous preorder and those fibrous preorders which return a topological space are called spatial. A… read more here.

Abstract: The existence of chaos and the quest of dense orbits have been recently considered for dynamical systems given by multivalued linear operators. We consider the notions of topological transitivity, topologically mixing property, hypercyclicity, periodic points,… read more here.

DOI: 10.3390/sym12030450
Abstract: In general, the group decompositions are formulated by employing automorphisms and semidirect products to determine continuity and compactification properties. This paper proposes a set of constructions of novel topological decompositions of groups and analyzes the… read more here.
