For a given single- or multivalued function and “atoms” , let be the set of all measurable selections of the function s \mapsto f(\lambda, s, x(s)) which are constant on each . It is discussed how this definition must be extended so that can serve as a right-hand side for PDEs when one is looking for weak solutions in Sobolev spaces. Continuity and differentiability of the corresponding operators are studied.
