Strict fixed point and stability results for multivalued operators via the admissible perturbation technique

Abstract We consider a class of multi-valued operators $$T:X\rightarrow P(X)$$ having the property that there exists an admissible perturbation of it, defined as $$T_G:X\rightarrow P(X)$$ and satisfying a Ćirić type contraction condition. This work focuses on the conditions impos...
