ملخص البحث:

The aim of this work is to prove some new fixed-point results for a class of weak 1-set contraction multi-valued mappings (with respect to some measure of weak noncompactness). The proofs employ weak compactness arguments and lie on some approximation argument. The results are then used to obtain some fixed point theorems for the sum of nonlinear operators. To illustrate the applicability of the theoretical result, we provide an example of application concerned with the solvability of a nonlinear integral inclusion with two Lipschitz-like nonlinearities.
