In this work, taking into account the -function, we present a general class of multivalued weakly Picard operators on complete metric space. We also provide an example showing that it includes some earlier classes as properly.
Mots-clés : Weakly Picard operator, multivalued mappings, $\theta$-contraction, fixed point.
