    1 - F-Closedness in Bitopological Spaces
    Journal of Linear and Topological Algebra , شماره 1 , سال 5 , زمستان 2016
    The purpose of this paper is to introduce the concept of pairwise F-closedness in bitopological spaces. This space contains both of pairwise strongcompactness and pairwise S-closedness and contained in pairwise quasi H-closedness. The characteristics and relationships c چکیده کامل
    The purpose of this paper is to introduce the concept of pairwise F-closedness in bitopological spaces. This space contains both of pairwise strongcompactness and pairwise S-closedness and contained in pairwise quasi H-closedness. The characteristics and relationships concerning this new class of spaces with other corresponding types are established. Moreover, several of its basic and important properties are discussed. پرونده مقاله

    2 - Some topological operators via grills
    Journal of Linear and Topological Algebra , شماره 4 , سال 5 , تابستان 2016
    In this paper, we define and study two operators $\Phi^s$ and $\Psi^s$ with grill. Characterizationand basic properties of these operators are obtained. Also, we generalize a grill topological spacesvia topology $\tau^s$ induced from operators $\Phi^s$ and $\Psi^s$.

    3 - Preclosure operator and its applications in general topology
    Journal of Linear and Topological Algebra , شماره 1 , سال 7 , زمستان 2018
    In this paper, we show that a pointwise symmetric pre-isotonic preclosurefunction is uniquely determined the pairs of sets it separates. We then showthat when the preclosure function of the domain is pre-isotonic and the pre-closure function of the codomain is pre-isoto چکیده کامل
    In this paper, we show that a pointwise symmetric pre-isotonic preclosurefunction is uniquely determined the pairs of sets it separates. We then showthat when the preclosure function of the domain is pre-isotonic and the pre-closure function of the codomain is pre-isotonic and pointwise-pre-symmetric,functions which separate only those pairs of sets which are already separatedare precontinuous. پرونده مقاله

    4 - Weak separation axioms via almost-ID-sets
    Journal of Linear and Topological Algebra , شماره 5 , سال 9 , پاییز 2020
    The purpose of this paper is to introduce some new classes of almost ideal topological spaces by using the notion of almost-$I$-open sets and study some of their fundamental properties. We study some low separation axioms in almost ideal topological spaces.
