Abstract
The purpose of this paper is to present a general answer for the following problem: Let (X, d) be a metric space and T1, T2 : X → P(X) two multifunctions. Determine the metric conditions which imply that (T1, T2) is a weakly Picard pair of multifunctions and T1, T2 are weakly Picard multifunctions , for multifunctions satisfying an implicit contractive condition, generalizing some results from [6] and [7].
