On a general contractive condition for cyclic self-mappings

This paper is concerned with p (≥2)-cyclic self-mappings t: ∩ i∈p̄ a i → ∩ i∈p̄i in a metric space (x,d),with a i ⊂ x,t(a i)⊆ a i+1 for i = 1,2,...,p,under a general contractive condition which includes as particular cases several of the existing ones in the literature. the existence and uniqueness of fixed points and best proximity points is discussed as well as the convergence to them of the iterates generated by the self-mapping from given initial points. copyright © 2011 m. de la sen.
