R. Parvathyparvathytopo@gmail.comS. Bhuvaneshwaribhuvi14495@gmail.com<p>In this paper, we have introduced the notion of reflexive retract. A few levels of retracts were achieved. The first level is obviously the retract in the sense of Borsuk, and the second level is reflexive homotopy and its properties.</p>2019-01-31T11:09:59+00:00Copyright (c) 2019 Modern Science Publishershttp://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1489A note on the lattice of L-topologies2019-04-04T23:59:08+00:00Pinky .pritammalik90@gmail.comT.P Johnsontpjohnson@cusat.ac.in<p>In this paper, we study the lattice structure of the lattice \(F_{T,L}\) of all \(L\)-topologies determined by the families of Scott continuous functions for a given topological space \((X,T)\). Some properties are discussed for which the lattice \(F_{T,L}\) is complemented.</p>2019-02-03T19:41:39+00:00Copyright (c) 2019 Modern Science Publishershttp://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1497Some strong forms of connectedness in topological spaces2019-04-04T23:59:08+00:00B.

Chauhanharsh.chauhan111@gmail.com<p>In this paper, we study new separations of sets called half separated, half \(\alpha\)-separated, half semi separated, half pre-separated, half \(\beta\)-separated sets and corresponding to these notions introduced half connected, half \(\alpha\)-connected, half semi-connected, half pre-connected, half \(\beta\)-connected topological spaces, respectively. These are stronger forms of connectedness, \(\alpha\)-connectedness, semi-connectedness, pre-connectedness, \(\beta\)-connectedness respectively. The properties of these notions follow the same pattern.</p>2019-02-03T00:00:00+00:00Copyright (c) 2019 Modern Science Publishershttp://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1507Compact and extremally disconnected spaces via generalized continuous functions2019-04-04T23:59:07+00:00Zeinab Bandpeybandpey65@gmail.comBhamini M. P. NayarBhamini.Nayar@morgan.edu<div class="page" title="Page 1"> <div class="layoutArea"> <div class="column"> <p>In [12], the class of compact and extremally dinconnected spaces were studied using several investigative tools such as filters, graphs, functions, multifuctions and subsets of the space. These different approaches of investigation produced significant charecterizations and properties of this important class of spaces. In [3] we introduced three forms of generalized continuous functions by studying the class of u-continuous functions of Joseph, Kwack and Nayar [9] using the concepts of an α-set of Njastad [13]. The generalized continuous forms introduced there are: αu-continuous, semi-αu-contnuous and strongly u-continuous functions. In the present study we investigate the class of compact and extremally disconnected spaces using these generalized continuous functions.</p> </div> </div> </div>2019-02-09T17:57:50+00:00Copyright (c) 2019 Modern Science Publishershttp://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1499Semi compactness in fuzzifying bitopological spaces2019-04-04T23:59:07+00:00A.

Binshahnahnull@null.com<p>In this paper, we dene semi open sets in the subspaces of fuzzifying bitopological spaces and study some properties of these sets. We introduce and study the concepts of semi-compactness in fuzzifying bitopological spaces. Also we give some properties of the semi-compactness in fuzzifying bitopological spaces.</p>2019-03-30T18:14:26+00:00Copyright (c) 2019 Modern Science Publishershttp://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1503Binary Cech closure spaces using binary ideals and binary grills2019-04-17T13:36:03+00:00Tresa Mary Chackotresachacko@gmail.comSusha D.sushad70@gmail.com<p>In this paper we introduce binary Cech closure operators obtained from binary ideals and binary grills.<br>Here we describe some properties of the binary topology obtained from both binary ideals and binary grills.<br>Also we present the concept of compactness in both binary ideals and binary grills.</p>2019-04-17T13:36:03+00:00Copyright (c) 2019 Modern Science Publishers
