A new perspective for multivalued weakly Picard operators [PDF]
Publications de l'Institut Mathematique, 2017 This research contains some recent developments about multivalued weakly Picard operators on complete metric spaces. In addition, taking into account both multivalued θ-contraction and almost contraction on complete metric spaces, we present a new ...

On multivalued weakly Picard operators in partial Hausdorff metric spaces [PDF]
Fixed Point Theory and Applications, 2015 We discuss multivalued weakly Picard operators on partial Hausdorff metric spaces. First, we obtain Kikkawa-Suzuki type fixed point theorems for a new type of generalized contractive conditions.

On a general class of weakly Picard operators [PDF]
Miskolc Mathematical Notes, 2015 In this paper we show that on complete metric spaces the class of weakly Picard operators contains some operators which are more general than the class of almost contractions.

Frum-Ketkov operators which are weakly Picard [PDF]
Carpathian Journal of Mathematics, 2020 In this paper, we will give sufficient conditions ensuring that a Frum-Ketkov operator is weakly Picard. Some generalized Frum-Ketkov operators are also studied.

Weakly Picard pairs of some multivalued operators [PDF]
Mathematical Communications, 2003 The purpose of this paper is to present a partial answer to the following problem: Let (X,d) be a metric space and $T_1,T_2:Xto P(X)$ two multivalued operators.

Some new fixed point results for multi-valued weakly Picard operators
Filomat, 2019 In this paper, we present some extensions of Banach contraction principle for multi-valued maps. Corresponding convergence theorems for the Picard iteration associated to a class of multi-valued operators are obtained in the setting of modular metric ...

A FIXED POINT THEOREM FOR MULTI-VALUED WEAKLY PICARD OPERATORS IN b-METRIC SPACE [PDF]
Demonstratio Mathematica, 2009 In this paper, we establish a fixed point theorem for multi-valued operators in a complete b−metric space using the concept of Berinde and Berinde [9] on multi-valued weak contractions for the Picard iteration in a metric space.

On Multi-Valued Weakly Picard Operators in Hausdorff Metric-Like Spaces
International Journal of Analysis and Applications, 2016 In this paper, we study multi-valued weakly Picard operators on Hausdorff metric-like spaces. Our results generalize some recent results and extend several theorems in the literature. Some examples are presented making effective our results.

On multivalued P-contractive mappings that belongs to class of weakly Picard operators [PDF]
Fixed Point Theory, 2021 Summary: In the present paper, by introducing the \(P\)-contractivity of a multivalued mapping, we give a new class of multivalued weakly Picard operators on complete metric spaces and show that the class of multivalued contractions is a proper subset of this new class. We also give a nontrivial example showing this fact.
