Convergence and existence results for best proximity points.
(English)
[J] Nonlinear Anal., Theory Methods Appl., Ser. A, Theory Methods 70, No. 10, A, 3665-3671 (2009). ISSN 0362-546X

Authors' summary: We provide a positive answer to a question raised by {\it A.\,A.\thinspace Eldred} and {\it P.\,Veeramani} [J.~Math.\ Anal.\ Appl.\ 323, No.\,2, 1001--1006 (2006; Zbl 1105.54021)] about the existence of a best proximity point for a cyclic contraction map in a reflexive Banach space. Moreover, we introduce a new class of maps, called cyclic $\varphi$-contractions, which contains the cyclic contraction maps as a subclass. Convergence and existence results of best proximity points for cyclic $\varphi$-contraction maps are also obtained.
