A unified theory of weak continuity for functions

V Popa, T Noiri - Rendiconti del Circolo Matematico di Palermo, 2002 - Springer
In this paper we introduce a new notion of weakly M-continuous functions as functions from
a set satisfying some minimal conditions into a set satisfying some minimal conditions. We …

On upper and lower M-continuous multifunctions

T Noiri, V Popa - Filomat, 2000 - JSTOR
In this paper we introduce upper/lower M-continuous multifunctions as a multifunction
defined between sets satisfying certain minimal conditions. We obtain some …

Weak and strong forms of β-irresolute functions

T Noiri - Acta Mathematica Hungarica, 2003 - Springer
A subset A of a topological space X is said to be β-open [1] if A⊂ Cl (Int (Cl (A))). A function f:
X→ Y is said to be β-irresolute [4] if for every β-open set V of Y, f-1 (V) is β-open in X. In this …

Properties of β-connected spaces

S Jafari, T Noiri - Acta Mathematica Hungarica, 2003 - Springer
Many characterizations of semipreconnected (= β-connected) spaces are obtained by Aho
and Nieminen [2]. In this paper, we obtain further characterizations of semipreconnected …

On almost β-continuous functions

T Noiri, V Popa - Acta Mathematica Hungarica, 1998 - Springer
A subset A of a topological space is said to be β-open [1] if A⊂ Cl (Int (Cl (A))). A function f:
X→ Y is said to be almost β-continuous [18] if for each point x∈ X and each open …

Faintly m-continuous functions

T Noiri, V Popa - Chaos, Solitons & Fractals, 2004 - Elsevier
We introduce a new class of functions called a faintly m-continuous function which is a
generalization of both faintly continuous functions [Kyungpook Math. J. 22 (1982) 7] and m …

Semi-open sets, preopen sets,-open sets,-open sets and-open sets play an important role in
the researches of generalizations of continuity in topological spaces. By using these sets …
