نویسندگان
چکیده
The existence of approximate fixed points and approximate endpoints of the multivalued almost I-contractions is established. We also develop quantitative estimates of the sets of approximate fixed points and approximate endpoints for multivalued almost I-contractions. The proved results unify and improve recent results of Amini-Harandi 2010 , M. Berinde and V. Berinde 2007 , Ćirić 2009 , M. Păcurar and R. V. Păcurar 2007 and many others.

Endpoints of set-valued asymptotic contractions in metric spaces
By introducing a new concept called ‘‘set-valued asymptotic contraction’’ in metric spaces, the existence and uniqueness of endpoints for a set-valued asymptotic contraction which has the approximate endpoint property have been established. © 2010 Elsevier Ltd. All rights reserved.
متن کاملA fixed point result for a new class of set-valued contractions
In this paper, we introduce a new class of set-valued contractions and obtain a xed point theoremfor such mappings in complete metric spaces. Our main result generalizes and improves many well-known xed point theorems in the literature.
متن کاملOn End and Coupled Endpoints of $theta$-$F$-Contractive Set-Valued Mappings
In this paper, we introduce a new concept in set-valued mappings which we have called condition $(UHS)$. Then, adding this condition to a new type of contractive set-valued mappings, recently has been introduced by Amini-Harandi [Fixed and coupled fixed points of a new type contractive set-valued mapping in complete metric spaces, Fixed point theory and applications, 215 (2012)], we prove that ...
متن کاملApproximation of endpoints for multi-valued mappings in metric spaces
In this paper, under some appropriate conditions, we prove some $Delta$ and strong convergence theorems of endpoints for multi-valued nonexpansive mappings using modified Agarwal-O'Regan-Sahu iterative process in the general setting of 2-uniformly convex hyperbolic spaces. Our results extend and unify some recent results of the current literature.
متن کاملFixed Sets and Endpoints of Set-valued Asymptotic Contractions in Metric Spaces
By introducing a new concept called “set-valued asymptotic contraction of final type” in metric spaces, the existence and uniqueness of compact fixed sets for such mappings have been obtained. Furthermore, by adding additional conditions, we prove the existence and uniqueness of endpoints for these maps. 2010 Mathematics Subject Classification: 47H10; 54C60
