Graded topological spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 2019
We introduce the notion of a "graded topological space": a topological space endowed with a sheaf of abelian groups which we think of as a sheaf of gradings.

Topological Quasilinear Spaces [PDF]

open access: yesAbstract and Applied Analysis, 2012
We introduce, in this work, the notion of topological quasilinear spaces as a generalization of the notion of normed quasilinear spaces defined by Aseev (1986). He introduced a kind of the concept of a quasilinear spaces both including a classical linear

Topological Test Spaces [PDF]

open access: yesInternational Journal of Theoretical Physics, 2004
A test space is the set of outcome-sets associated with a collection of experiments. This notion provides a simple mathematical framework for the study of probabilistic theories -- notably, quantum mechanics -- in which one is faced with incommensurable ...

Announcement as effort on topological spaces. [PDF]

open access: yesSynthese, 2019
We propose a multi-agent logic of knowledge, public and arbitrary announcements, that is interpreted on topological spaces in the style of subset space semantics. The arbitrary announcement modality functions similarly to the effort modality in subset space logics, however, it comes with intuitive and semantic differences.

The Rice-Shapiro theorem in Computable Topology [PDF]

open access: yesLogical Methods in Computer Science, 2017
We provide requirements on effectively enumerable topological spaces which guarantee that the Rice-Shapiro theorem holds for the computable elements of these spaces.

Disjoint union of fuzzy soft topological spaces

open access: yesAIMS Mathematics, 2023
In this work, sums of fuzzy soft topological spaces are defined with free union of a pairwise disjoint non-empty family of fuzzy soft topological spaces. Firstly, we give general information of fuzzy soft topological spaces. Then, we define free union of

Fibrewise Fuzzy Topological Spaces

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2021
We introduce and discuss the modern type of fibrewise topological spaces, namely fibrewise fuzzy topological spaces. Also, we introduce the concepts of fibrewise closed fuzzy topological spaces, fibrewise open fuzzy topological spaces, fibrewise locally ...

On the Structure of Topological Spaces [PDF]

open access: yesAxioms, 2022
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 special class of spatial fibrous preorders consisting of an interconnected family of preorders indexed by a unitary ...
