On selections of multifunctions

Milan Matejdes (1993)

Mathematica Bohemica

Similarity:

The purpose of this paper is to introduce a definition of cliquishness for multifunctions and to study the search for cliquish, quasi-continuous and Baire measurable selections of compact valued multifunctions. A correction as well as a generalization of the results of [5] are given.

On the cliquish, quasicontinuous and measurable selections

Milan Matejdes (1991)

Mathematica Bohemica

Similarity:

The purpose of this paper is the investigation of the necessary and sufficient conditions under which a given multifunctions admits a cliquish and measurable selection. Our investigation also covers the search for quasicontinuous selections for multifunctions which are continuous with respect to the generalized notion of the semi-quasicontinuity.
