MORPHOLOGICAL SAMPLING OF CLOSED SETS

open access: yesImage Analysis & Stereology, 2011
We briefiy survey the standard morphological approach (Heijmans, 1994) to the sampling (or discretization) of sets. Then we summarize the main results of our metric theory of sampling (Ronse and Tajine, 2000; 2001; 2002; Tajine and Ronse, 2002), which can be used to analyse several sampling schemes, in particular the morphological one.

The Closure Operator with the Equality Predicate Branching on the Set of Hyperfunctions on Two-Element Set

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2014
In this work we consider the closure operator with the equality predicate branching (E-operator) on the set of hyperfunctions on two-element set. With respect to this operator closed classes of hyperfunctions are generated.

Neutrosophic Closed Set and Neutrosophic Continuous Functions [PDF]

open access: yesNeutrosophic Sets and Systems, 2014
In this paper, we introduce and study the concept of "neutrosophic closed set "and "neutrosophic continuous function". Possible application to GIS topology rules are touched upon.

A Decomposition of \alpha-continuity and \mu\alpha-continuity

open access: yesJournal of New Theory, 2020
The main purpose of this paper is to introduce the concepts of *\eta-sets, **\eta-sets, *\eta-continuity and **\eta-continuity and to obtain decomposition of \alpha-continuity and \mu\alpha-continuity in topological spaces.

Between semi-closed sets and semi-pre-closed sets

open access: yes, 2000
The author introduces a new class of generalized closed sets which he calls \(\psi\)-closed sets. A subset \(A\) of a topological space \(X\) is said to be \(\psi\)-closed if \(\text{scl}(A) \subseteq U\) whenever \(A\subseteq U\) and \(U\) is sg-open in \(X\).

g¨-LOCALLY CLOSED SETS IN TOPOLOGICALSPACES

open access: yesJournal of New Theory, 2015
− The aim of this paper is to introduce and study the classes of ¨g-locally closed sets, ¨g-lc?sets and ¨g-lc??sets which are weaker forms of the class of locally closed sets.

Fuzzy tgp-closed sets and fuzzy t^* gp-closed sets

open access: yesInternational Journal of Engineering & Technology, 2018
In this paper, we aim to address the idea of fuzzy -set and fuzzy -set in fuzzy topological space to present new types of the fuzzy closed set named fuzzy -closed set and fuzzy -closed set. We will study several examples and explain the relations of them with other classes of fuzzy closed sets.
