On Semi pre-generalized-closed sets
Wasit Journal for Pure Sciences, 2022 In this paper, a new class of called semi-pre-generalised closed set in topological space are introduced and studied. Also some of their properties have been investigated.

Perception of Nano Generalized t#-Closed Sets
Journal of New Theory, 2018 In this paper, we introduce a new class of sets called nt#g-closed sets, which isstronger than ng-closed sets and weaker than n-closed ...

Open Set Logo Detection and Retrieval
, 2017 Current logo retrieval research focuses on closed set scenarios. We argue that the logo domain is too large for this strategy and requires an open set approach.

Journal of New Theory, 2016 − In this paper, we introduce the notion of I ∗ ∗g -closed sets and prove that this class of sets is stronger than the class of gs∗ I -closed sets as well as the class of Ig-closed sets. Characterizations and properties of I ∗ ∗g -closed sets and I ∗ ∗g -

Some Properties of Interior and Closure in General Topology
Mathematics, 2019 We present the necessary and sufficient conditions that the intersection of an open set and a closed set becomes either an open set or a closed set. As their dualities, we further introduce the necessary and sufficient conditions that the union of a ...

Lines in higgledy-piggledy position [PDF]
, 2014 We examine sets of lines in PG(d,F) meeting each hyperplane in a generator set of points. We prove that such a set has to contain at least 1.5d lines if the field F has more than 1.5d elements, and at least 2d-1 lines if the field F is algebraically ...

Computing metric hulls in graphs
, 2018 We prove that, given a closure function the smallest preimage of a closed set can be calculated in polynomial time in the number of closed sets. This confirms a conjecture of Albenque and Knauer and implies that there is a polynomial time algorithm to ...

On generalized b*-Closed Sets In Topological Spaces
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017 In this paper, we introduce and study the concept of a new class of generalized closed set which is called generalized b*-closed set in topological spaces ( briefly .g b*-closed) we study also.

On Hausdorff dimension of the set of closed orbits for a cylindrical transformation
, 2010 We deal with Besicovitch's problem of existence of discrete orbits for transitive cylindrical transformations $T_\varphi:(x,t)\mapsto(x+\alpha,t+\varphi(x))$ where $Tx=x+\alpha$ is an irrational rotation on the circle $\T$ and $\varphi:\T\to\R$ is ...

Λg-CLOSED SETS WITH RESPECT TO AN IDEAL
Journal of New Theory, 2015 − In this paper, the notions of IΛg-closed sets and IΛg-open sets are introduced. Characterizations and properties of such notions are obtained.
