On almost quasicontinuous functions

Ján Borsík (1993)

Mathematica Bohemica

Similarity:

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

Quasicontinuity and related properties of functions and multivalued maps

Janina Ewert (1995)

Mathematica Bohemica

Similarity:

The main results presented in this paper concern multivalued maps. We consider the cliquishness, quasicontinuity, almost continuity and almost quasicontinuity; these properties of multivalued maps are characterized by the analogous properties of some real functions. The connections obtained are used to prove decomposition theorems for upper and lower quasicontinuity.
