On almost quasicontinuity [PDF]
summary:The concept of almost quasicontinuity is investgated in this paper in several directions (e.g. the relation of this concept to other generalizations of continuity is described, various types of convergence of sequences of almost quasicontinuous ...

ON GENERALIZED ALMOST CONTRA CONTINUOUS FUNCTIONS AND SOME RELATIONS WITH ANOTHER KINDS OF CONTINUITY ON INTUITIONISTIC TOPOLOGICAL SPACES [PDF]
We study in this paper the concept of almost contra continuous functions and generalized them in intuitionistic topological spaces and we studied the relations of each kind of these function by properties, examples and a diagram to summarize these ...

Upper and Lower Weakly α-*-Continuous Multifunctions
This paper deals with the concepts of upper and lower weakly α-*-continuous multifunctions. Moreover, some characterizations of upper and lower weakly α-*-continuous multifunctions are investigated.

A Meir-Keeler type fixed point theorem for a family of mappings is proved in Menger probabilistic metric space (Menger PM-space). We establish that completeness of the space is equivalent to fixed point property for a larger class of mappings that ...

Every almost continuous function is polygonally almost continuous.
A function \(f: \mathbb{I} \rightarrow \mathbb{R}\) is almost continuous (AC) if whenever \(U\subset \mathbb{I} \times \mathbb{R}\) is an open set containing the graph of \(f\), then \(U\) contains the graph of a continuous function. A function \(f: \mathbb{I} \rightarrow \mathbb{R}\) is polygonally almost continuous (PAC) if whenever \(U\subset ...

ALMOST WEAKLY CONTINUOUS MULTIFUNCTION
\textit{N. Levine} [Am. Math. Mon. 68, 44-46 (1961; Zbl 0100.18601)] introduced the concept of weakly continuous functions in topological spaces. \textit{T. Husain} [Prace Mat. 10, 1-7 (1966; Zbl 0138.17601)] introduced the concept of almost continuous functions. \textit{R. E. Smithson} [Bull. Calcutta Math. Soc. 70, 383-390 (1978; Zbl 0445.54006)] and

Mappings and decompositions of continuity on almost Lindelöf spaces
A topological space X is said to be almost Lindelöf if for every open cover {Uα:α∈Δ} of X there exists a countable subset {αn:n∈ℕ}⊆Δ such that X=∪n∈ℕCl(Uαn).

ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.

δω-Continuity and some Results on δω-Closure Operator
Al-Jarrah et al. defined a new topological operator, namely, δω-closure operator, and proved that it lies between the δ-closure operator and the usual closure operator. Al-Ghour et al. defined θω-closure operator and discussed its properties.

Subweakly α-continuous functions
In a recent paper by T. Noiri [1], a function f:X→Y is said to be weakly α-continuous if f:Xα→Y is weakly continuous where Xα is the space X endowed with the α-topolooy.
