Existence theorems for inclusions of the type $$\psi(u)(t)\in F(t,\phi(u)(t))$$. (English) Zbl 1027.47063
Existence results for operator inclusions in Banach spaces are studied. The obtained results are a generalization of earlier results proved by O. Naselli, B. Ricceri and the authors. The main tool for proving their results is the Ky Fan fixed point theorem.
