A Unification on Compactness and Closedness by Mahi̇de Küçük and İdri̇s Zorlutuna

چکیده
Compactness and closedness are some of the important properties for studying topological spaces. Several types of these concepts (semi-compactness, pre-compactness, β-compactness,. . ., S-closedness, H-closedness, etc) occur in the literature. In this paper, we applied concept of φ operation which defined by Csaszar [8] to unify and generalized several characterizations and properties of lots of already existing some type of compactness and closedness.

A UNIFIED THEORY FOR WEAK SEPARATION PROPERTIES MAHIDE KÜÇÜK and İDṘIS ZORLUTUNA
We devise a framework which leads to the formulation of a unified theory of normality (regularity), semi-normality (semi-regularity), s-normality (s-regularity), feeblynormality (feebly-regularity), pre-normality (pre-regularity), and others. Certain aspects of theory are given by unified proof.
متن کاملStrong Compactness and P-Closedness in Smooth L-Fuzzy Topological Spaces
In this work, we introduce definitions of smooth strong compactness and smooth P-closedness for arbitrary L-fuzzy sets in smooth Lfuzzy topological spaces and study some of their properties. We also investigate relations between these concepts and the other definitions of compactness in smooth L-fuzzy spaces. Mathematics Subject Clasification: 54A40
متن کاملCompactness, Perfectness, Separation, Minimality and Closedness with Respect to Closure Operators
In this paper, the characterization of closed and strongly closed subobjects of an object in categories of various types of filter convergence spaces is given and it is shown that they induce a notion of closure. Furthermore, each of the notions of compactness, perfectness, separation, minimality and absolute closedness with respect to these two new closure operators are characterized in these ...
متن کاملA note on gradation of RS-compactness and S*-closed spaces in L-topological spaces
In this paper we define gradation of RS-compactness and S*-closed spaces in L-topological spaces.We generalize the degrizations of RS-compactness and S*-closedness to the L-topological space and give the positions of them under weak forms of L-continuity. 2010 AMS Classification: 54A40, 06D72
متن کاملA Study on the Attitude of Students of I.A.U of Religion 11 on National Unity and Islamic Unification
Because of its structure and cultural, social and historical conditions, the country of Iran has various ethnic, religious, and racial types. On the other hand, as an element of large Islamic nation, Iran encounters various complex cultural conditions. The nature and the origin of unity and unification are the common points between these organs at both national and Islamic nation's level. In f...
