Contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions
The notion of contra continuous functions was introduced and investigated by Dontchev. In this paper, we apply the notion of $beta^{*}$-closed sets in topological space to present and study a new class of functions called contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions as a new generalization of contra continuity.
متن کاملFuzzy Almost Continuous Functions
In this paper, we further study properties of fuzzy almost continuous functions in Singal’s and Hussain’s sense and establish a condition for their equivalence which is an improvement of Theorem 5.5 of [2]. Some divergences from straightforward fuzzification of General Topology have also been noted in Example 1 and Theorem 4. We also define fuzzy almost weakly continuous and fuzzy nearly almost...
متن کاملOn Some Properties of Sets Blocking Almost Continuous Functions
We define operators E( · ) and N ( · ) for blocking sets for almost continuous functions. Using language of these operators we give new proofs for some classical theorems and prove some new theorems. Finally, we make some remarks regarding uniform limits of almost continuous functions.
متن کاملAlmost Slightly νg−Continuous Functions
In this paper we discuss a new type of continuous functions called almost slightly νg−continuous functions; its properties and interrelation with other continuous functions are studied.
متن کاملTwo examples concerning almost continuous functions
In this note we will construct, under the assumption that union of less than continuum many meager subsets of R is meager in R, an additive connectivity function f : R → R with Cantor intermediate value property which is not almost continuous. This gives a partial answer to a question of D. Banaszewski [2]. (See also [12, Question 5.5].) We will also show that every extendable function g : R → ...
