On soft p c-separation axioms

Demonstratio Mathematica, 2020
Many mathematicians defined and studied soft separation axioms and soft continuity in soft spaces by using ordinary points of a topological space X. Also, some of them studied the same concepts by using soft points.

Limits of Sequences of Feebly-Type Continuous Functions

Annales Mathematicae Silesianae, 2020
We consider the following families of real-valued functions defined on 𝕉2: feebly continuous functions (FC), very feebly continuous functions (VFC), and two-feebly continuous functions (TFC). It is known that the inclusions FC ⊂ VFC ⊂ TFC are proper.

Projective versions of the properties in the Scheepers Diagram [PDF]

, 2020
Let $\mathcal{P}$ be a topological property. A.V. Arhangel'skii calls $X$ projectively $\mathcal{P}$ if every second countable continuous image of $X$ is $\mathcal{P}$. Lj.D.R.

Notes on Fuzzy Parametrized Soft Sets

Cumhuriyet Science Journal, 2018
In this paper, we introduced the notion of inverse Fpsoft set and studied some properties of it. Moreover, by using this new conceptwe characterized the continuity of Fp soft mappings and continuity of fuzzysoft mapping.

A selection theorem for simplex-valued maps [PDF]

, 2004
The purpose of this short note is to prove the following theorem. Let X be a hereditarily normal paracompact Hausdorff space, K be a simplicial complex, and : X K be a function.

On topological structures of fuzzy parametrized soft sets [PDF]

, 2014
In this paper, we introduce the topological structure of fuzzy parametrized soft sets and fuzzy parametrized soft mappings. We define the notion of quasi-coincidence for fuzzy parametrized soft sets and investigated basic properties of it.

Diagonals of separately continuous maps with values in box products

Topological Algebra and its Applications, 2018
We prove that if X is a paracompact connected space and Z = ∏s∈S Zs is a product of a family of equiconnected metrizable spaces endowed with the box topology, then for every Baire-one map g : X → Z there exists a separately continuous map f : X2 → Z such

On the class of weakly almost contra-T*-continuous functions [PDF]

, 2019
The aim of this paper is to introduce and investigate a new class of functions called weakly almost contra-$T^*$-continuity which is defined as a function from an operator topological space $(X, \tau, T)$ into an arbitrary topological space $(Y, \delta)$.
