Abstract: This investigation includes for the first time, as part of an ongoing research, a new chemical compound and main constituents isolated from P. nestorianus and bioassay evaluation. In fact,…
Abstract: The purpose of the present work is to introduce and investigate a new class of sets called (i, j)-Ps– open sets, and use this class to define and study…
Abstract: The purpose of the present work is to introduce and investigate some of the new topological concepts by using the class of Sp-open sets such as Sp-closed spaces,…
Abstract: In this work we introduce and study a new class of open sets by means semi‐open sets [16] and preclosed sets [8] called Sp‐open sets. By the above…
Abstract: In this work we continue to investigate the properties of soft semi-open and soft semi-closed sets in soft topological spaces. We define a new type of soft semi-open and…
Abstract: Let be an associative ring with identity and M be a non-zero unitary left module over . is called a hollow (semihollow) module if every proper ( finitely generated…
Abstract: The main purpose of the present work is to introduce and study a new class of semi-open sets called -open sets. We use this set to study new topological…
Abstract: The purpose of the present work is to introduce and investigate a new class of sets in a topological spaces called S – open sets. We use this set…
Abstract: The purpose of the present work is to define and study new classes of the most well-known concepts of topological space, such as continuity and separation ax- ioms called…
Abstract: Introducing and investigating a new class of sets called Pp -open sets is the main aim of this work and using this set we define and study new classes…
