Non-autonomous vector integral equations with discontinuous right-hand side. (English) Zbl 1055.45004

An existence of an \(L^s\)-solution, \(s\in \, ]1, \infty ]\), is proved for the integral equation \[ u(t) = f\left(t, \int _I g(t,z)u(z)\,dz\right), \] where \(f\) is not necessarily continuous in the second variable. The result is obtained by transforming the original problem to the one for a certain operator inclusion. Thus, another result of this type obtained earlier by the author jointly with F. Cammaroto in [Commentat. Math. Univ. Carolin. 40, 483–490 (1999; Zbl 1065.47505)] is generalized.
