Here we examine some semi-separation axioms which are carried from subspaces to parent spaces with the help of invertibility and semi-invertibility. Also we study these properties on completely invertible and completely semi-invertible spaces.</p>2019-10-03T14:22:32+00:00Copyright (c) 2019 Modern Science Publishershttp://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1580More on \(P\)-closed spaces2019-12-08T07:55:32+00:00Terrence A. Edwardstedwards@udc.eduJames E. Josephj122437@yahoo.comBhamini M.P. Nayarbhaminin@yahoo.com<p>In [1] the following problems were listed as open: Problem 14. Is a regular space in which every closed subset is regular-closed compact? Problem 15. Is a Urysohn-space in which every closed subset is Urysohnclosed compact? To answer the question for Hausdorff-closed spaces in the affirmative, M. H. Stone [12] used Boolean rings and M. Katˇetov [10] used topological methods. In this article, all three questions are answered affirmatively using filters.</p>2019-11-09T21:25:30+00:00Copyright (c) 2019 Modern Science Publishershttp://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1601Some multi-valued contraction theorems on \(\mathcal{H}\)-cone metric2019-12-21T18:43:44+00:00Saif Ur Rehmannull@null.comShamoona Jabeenbshamoonaafzal@yahoo.comMuhammad .null@null.comHayat Ullahnull@null.comHanifullah .null@null.com<p>In this paper we define some new type of multi-valued contraction maps on \(\mathcal{H}\)-cone metric and proved some fixed point and common fixed point theorems in the setting of cone metric spaces.</p>2019-12-21T18:43:43+00:00Copyright (c) 2019 Modern Science Publishershttp://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1595Huber's theorem and some results in bispaces2020-03-12T05:07:49+00:00Sushanta Kumar Mohantasmwbes@yahoo.inShilpa Patrashilpapatrabarasat@gmail.com<p>In this paper, we obtain a generalized version of Huber’s theorem in a suitable bispace and analyse some properties of the limit map of a sequence of continuous maps over such a bispace.</p>2020-02-28T11:46:27+00:00Copyright (c) 2020 Modern Science Publishers
