#### Abstract

We prove, under some general assumptions, that a generator of any uniformly bounded Nemytskij operator, mapping a subset of space of functions of bounded variation in the sense of Wiener-Young into another space of this type, must be an affine function with respect to the second variable.

#### Keywords

${\varphi}$-variation in the sense of Wiener;uniformly bounded operator;regularization;composition operator;Jensen equation
