http://www.m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1575
<p>In this paper we introduce the concept of semi-invertibility with respect to a semi-open set. 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>Neethu M, Anjaly Jose

http://www.m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1580
<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. KatĖetov [10] used topological methods. In this article, all three questions are answered affirmatively using filters.</p>Terrence A. Edwards, James E. Joseph, Bhamini M.P. Nayar

http://www.m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1601
<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>Saif Ur Rehman, Shamoona Jabeenb, Muhammad ., Hayat Ullah, Hanifullah .
