Computably Based Locally Compact Spaces [PDF]

open access: yesLogical Methods in Computer Science, 2006
ASD (Abstract Stone Duality) is a re-axiomatisation of general topology in which the topology on a space is treated, not as an infinitary lattice, but as an exponential object of the same category as the original space, with an associated lambda-calculus.

Two new forms of ordered soft separation axioms

open access: yesDemonstratio Mathematica, 2020
The goal of this work is to introduce and study two new types of ordered soft separation axioms, namely soft Ti-ordered and strong soft Ti-ordered spaces (i = 0, 1, 2, 3, 4).

Positive answers to Koch’s problem in special cases

open access: yesTopological Algebra and its Applications, 2020
A topological semigroup is monothetic provided it contains a dense cyclic subsemigroup. The Koch problem asks whether every locally compact monothetic monoid is compact.

Notes on Fuzzy Parametrized Soft Sets

open access: yesCumhuriyet 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.

On Coron's problem for the p-Laplacian [PDF]

open access: yes, 2014
We prove that the critical problem for the $p$-Laplacian operator admits a nontrivial solution in annular shaped domains with sufficiently small inner hole.

Coloring Cantor sets and resolvability of pseudocompact spaces [PDF]

open access: yes, 2017
Let us denote by $\Phi(\lambda,\mu)$ the statement that $\mathbb{B}(\lambda) = D(\lambda)^\omega$, i.e. the Baire space of weight $\lambda$, has a coloring with $\mu$ colors such that every homeomorphic copy of the Cantor set $\mathbb{C}$ in $\mathbb{B}(\

SEVERAL NOTIONS OF GENERALIZED SEMI-COMPACTNESS IN DOUBLE FUZZY TOPOLOGICAL SPACES

open access: yes, 2016
The purpose of this paper is to introduce the notions of several types of semicompactness in double fuzzy topological spaces known as generalized double fuzzy semicompactness, generalized double fuzzy nearly semi-compactness and generalized double fuzzy ...

On locally compact semitopological O-bisimple inverse ω-semigroups

open access: yesTopological Algebra and its Applications, 2018
We describe the structure of Hausdorff locally compact semitopological O-bisimple inverse ω- semigroups with compact maximal subgroups. In particular, we show that a Hausdorff locally compact semitopological O-bisimple inverse ω-semigroup with a compact ...
