An existence theorem for the Urysohn integral equation in Banach spaces. (English) Zbl 0546.45011

By applying fixed point theorems and measures of non-compactness, the author proves the solvability of a nonlinear integral equation of Urysohn type in a generalized Orlicz space of Banach-space valued functions.
