Tytuł:: Uniformly continuous composition operators in the space of functions of two variables of bounded \(\varphi\)-variation in the sense of Wiener

Merentes, N.
Powiązania:: https://bibliotekanauki.pl/articles/745206.pdf
Data publikacji:: 2010
Wydawca:: Polskie Towarzystwo Matematyczne
Tematy:: \(\vaprhi\)-variation in the Wiener sense
composition operator
uniformly continuous operator
left-left regularization
Jensen equation
Opis:: Assume that the generator of a Nemytskii composition operator is a function of three variables: the first two real and third in a closed convex subset of a normed space, with values in a real Banach space. We prove that if this operator maps a certain subset of the Banach space of functions of two real variables of bounded Wiener \(\varphi\)-variation into another Banach space of a similar type, and is uniformly continuous, then the one-sided regularizations of the generator are affine in the third variable.

Tytuł:: On Banach spaces of regulated functions
Autorzy:: Drewnowski, Lech
Powiązania:: https://bibliotekanauki.pl/articles/1912831.pdf
Data publikacji:: 2017
Wydawca:: Polskie Towarzystwo Matematyczne
Tematy:: Regulated function
left- and right-continuity
Banach spaces
\(c_0(S)\) spaces
triple Sorgenfrey line
Alexandrov--Urysohn constructions
\(C(K)\) spaces, isomorphisms
Opis:: For a relatively compact subset \(S\) of the real line \(\BR\), let \(R(S)\) denote the Banach space (under the sup norm) of all regulated scalar functions defined on \(S\). The purpose of this paper is to study those closed subspaces of \(R(S)\) that consist of functions that are left-continuous, right-continuous, continuous, and have a (two-sided) limit at each point of some specified disjoint subsets of \(S\). In particular, some of these spaces are represented as \(C(K)\) spaces for suitable, explicitly constructed, compact spaces \(K\).
