On Verifying and Engineering the Well-gradedness of a Union-closed Family
, 2008 Current techniques for generating a knowledge space, such as QUERY, guarantees that the resulting structure is closed under union, but not that it satisfies wellgradedness, which is one of the defining conditions for a learning space.

DECOMPOSITIONS OF TOPOLOGICAL FUNCTIONS
Journal of New Theory, 2016 Abstaract−We obtain new classes of sets by using λ-closed sets in topological spaces and study their basic properties; and their connections with other kind of topological sets.

A combinatorial model for the free loop fibration
, 2018 We introduce the abstract notion of a closed necklical set in order to describe a functorial combinatorial model of the free loop fibration $\Omega Y\rightarrow \Lambda Y\rightarrow Y$ over the geometric realization $Y=|X|$ of a path connected simplicial

Between *-Closed Sets and Iw-Closed Sets
Journal of New Results in Science, 2013 –closed sets ( Iω-closed sets ) and further properties of Iˆg-closedsets are investigated. In this paper, we introduce the notion ofImω-closed sets and obtain the unified characterizations for certain families of subsets between -closed sets and Iω-closed setsin an ideal topological ...

New topological approach of generalized closed sets
Journal of New Results in Science, 2015 Closedness is a basic concept for the study and the investigation in the general topological spaces. (Fukutake, Nasef and El- Maghrabi, 2003) introduced a new weakly form of generalized closed sets,γg−closed set, which is weaker than both of gs−closed ...

Closed sets without measurable matching [PDF]
Proceedings of the American Mathematical Society, 1988 We construct a rectangle in the unit square such that its perimeter contains a matching (i.e. the graph of a bijection of the unit interval onto itself) but does not contain a Borel matching or a matching measurable with respect to the linear measure.

Journal of New Theory, 2018 In this paper, we define and study the properties of a nano πgα-closed set which isa weaker form of a nano πg-closed set but strong than a nano πgp-closed sets and we define a newclass of sets called nano πgα-closed sets and some of their properties ...

C2AE: Class Conditioned Auto-Encoder for Open-set Recognition
, 2019 Models trained for classification often assume that all testing classes are known while training. As a result, when presented with an unknown class during testing, such closed-set assumption forces the model to classify it as one of the known classes ...

EXTENSIONS GENERATED BY CLOSED SETS
Tamkang Journal of Mathematics, 1993 From the nonempty collection of all closed sets $(Y)$ of any topological space $(X , \tau)$, Schmidt generates a topological space $(Y,\mathcal{U})$. In this paper, we give some properties of this topological space. We determined when $(f,(Y,\mathcal{U}))$ is an extension of $(X , \tau)$.

Известия Иркутского государственного университета: Серия "Математика", 2019 Multioperations are operations from a finite set A to set of all subsets of A. The usual composition operator leads to a continuum of closed sets. Therefore, the research of closure operators, which contain composition and other operations becomes ...
