Block Iterative Methods for a Finite Family of Relatively Nonexpansive Mappings in Banach Spaces

<p/> <p>Using the convex combination based on Bregman distances due to Censor and Reich, we define an operator from a given family of relatively nonexpansive mappings in a Banach space. We first prove that the fixed-point set of this operator is identical to the set of all common fixed p...
