Fixed point theory for multivalued φ-contractions

open access: yesFixed Point Theory and Applications, 2011
The purpose of this paper is to present a fixed point theory for multivalued φ-contractions using the following concepts: fixed points, strict fixed points, periodic points, strict periodic points, multivalued Picard and weakly Picard operators ...

On almost duality for Frobenius manifolds

open access: yes, 2003
We present a universal construction of almost duality for Frobenius manifolds. The analytic setup of this construction is described in details for the case of semisimple Frobenius manifolds.

open access: yes
In this paper we give a xed point results for multivalued operators on generalized metric spaces endowed with a generalized w-distance. Then we study the data dependence for this new result.multivalued weakly Picard operator, w-distance, fxed point ...

Common fixed point for generalized set valued contractions satisfying an implicit relation in partially ordered metric spaces [PDF]

open access: yes, 2010
Let $(X,d,preceq )$ be a partially ordered metric space. Let F, G be two set valued mappings on $X$. We obtained sufficient conditions for the existence of a common fixed point of F, G satisfying an implicit relation in ...
