On almost discrete space

Ali Akbar Estaji (2008)

Archivum Mathematicum

Let C ( X ) be the ring of real continuous functions on a completely regular Hausdorff space. In this paper an almost discrete space is determined by the algebraic structure of C ( X ) . The intersection of essential weak ideal in C ( X ) is also studied.

On almost quasicontinuity

Anna Neubrunnová, Tibor Šalát (1992)

Mathematica Bohemica

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 function are studied, a.s.o.).

On almost quasicontinuous functions

Ján Borsík (1993)

Mathematica Bohemica

A function f : X Y is said to be almost quasicontinuous at x X if x C I n t C f - 1 ( V ) for each neighbourhood V of f ( x ) . Some properties of these functions are investigated.

On an affirmative answer to Y. Tanaka's and Y. Ge's problem

Luong Quoc Tuyen (2017)

Commentationes Mathematicae Universitatis Carolinae

In this paper, we give an affirmative answer to the problem posed by Y. Tanaka and Y. Ge (2006) in "Around quotient compact images of metric spaces, and symmetric spaces", Houston J. Math. 32 (2006) no. 1, 99-117.
