New classes of functions, called somewhat -continuous, somewhat lambda-open and hardly -open functions, has been dened and studied by making use of lambda-open sets. Characterizations and properties of these functions are presented.

In this paper we define and study the concept of pre-Rg-continuous functionsusing preopen sets due to Mashhour et.al (1982) and rg-open sets due to N . Palaniappan(1993). Also,we study the pre-g-regular spaces. Mathematics Subject Classification(2010

On Weak Forms of Semi-Open and Semi-Closed Functions

Autor: Govindappa Navalagi, Miguel Caldas

Publikováno v: Missouri J. Math. Sci. 18, iss. 3 (2006), 165-178

Weakly semi-open functions between topological spaces are defined as dual to the weak semi-continuous. Connections between this function and other existing topological notions are established and separate examples are given. It is shown that weakly s

In this paper, we introduce and characterize fuzzy weakly semiopen functions between fuzzy topological spaces as natural dual to the fuzzy weakly semicontinuous functions and also study these functions in relation to some other types of already known
