In this paper we present new forms of the classical separation axioms on topological spaces. Our constructions generate a method to refine separation properties when passing to the quotient space and our results may be useful in the study of algebraic topological structures, such as topological groups and topological vector spaces.

following are the axioms of Zermelo and Fraenkel minus the axiom of infinity. (1). Schema of Specification (separation, restricted comprehension). Let φ(x, p). I am slightly confused since in the notes we are only really given the definition of the Axiom Schema of Separation and then there are no real examples. reject (e.g., Kripke's Schema) and is falsified outright by principles.

In this paper, the relationships of induced L-convex spaces with L-hull operators, product spaces, and quotient are discussed. It is shown that structure exactly by convex structure. Moreover, sub-S1, sub- S2, S2 S3 separation axioms introduced in spaces. Some properties them investigated.

The main purpose of our paper, is to investigate more properties of the soft β-separation axioms given in [8]. We show that, the properties of soft β-Ti-spaces (i = 1, 2) are soft topological properties under the bijection and irresolute open soft mapping. Also, the property of being soft βregular and soft β-normal are soft topological properties under bijection, irresolute soft and irresolute ...

Many scientists have studied and improved the soft set theory, which is initiated by Molodtsov [33] and easily applied to many problems having uncertainties from social life. The main purpose of our paper, is to introduce new soft separation axioms based on the b-open soft sets which are more general than of the open soft sets. We show that, the properties of soft b-Ti-spaces (i = 1,2) are soft...

Shabir and Naz in [25] introduced the notion of soft topological spaces. They defined basic notions of soft topological spaces such as open soft sets, closed soft sets, soft subspaces, soft closure, soft nbd of a soft point, soft separation axioms, soft regular spaces, soft normal spaces and they established their several properties. Min in [19] investigated some properties of such soft separat...

In this paper, separation and regularity axioms in fuzzy topology on fuzzy set are defined and studied. We investigate some of its characterizations and discuss certain relationship among them with some necessary counterexamples. Moreover some of their basic properties are examined. In addition, goodness and hereditary properties are discussed.

The fuzzy concept has invaded all branches of Mathematics ever since the introduction of fuzzy set by Zadeh [10]. Fuzzy sets have applications in many fields such as information [5] and control [8]. The theory of fuzzy topological spaces was introduced and developed by Chang [3] and since then various notions in classical topology have been extended to fuzzy topological spaces. Sostak [6] intro...
