1. Monotone approximation of measurable multifunctions by simple multifunctions Creator: Kubiś, Beata Format: bez média and svazek Type: model:article and TEXT Subject: measurable multifunction, Marczewski function, Vietoris topology, and simple multifunction Language: English Description: We investigate the problem of approximation of measurable multifunctions by monotone sequences of measurable simple ones. Our main tool is the Marczewski function, i.e., the characteristic function of a sequence of sets. Rights: http://creativecommons.org/publicdomain/mark/1.0/ and policy:public
