Let be a metric space, , , the gap functional, given by
and let be a multivalued operator. The fixed point inclusion
is said to be generalized Ulam-Hyers stable if and only if there exists an increasing function , continuous at 0 and with such that for each and for each solution of of the inequality
there exists a solution of the fixed point inclusion such that
In the paper under review, the authors establish generalized Ulam-Hyers stability results for fixed point problems as well as for coincidence point problems with multivalued operators.
