The Split Common Fixed Point Problem for Directed Operators

J Convex Anal. 2010 May 1;26(5):55007. doi: 10.1088/0266-5611/26/5/055007.

Abstract

We propose the split common fixed point problem that requires to find a common fixed point of a family of operators in one space whose image under a linear transformation is a common fixed point of another family of operators in the image space. We formulate and analyze a parallel algorithm for solving this split common fixed point problem for the class of directed operators and note how it unifies and generalizes previously discussed problems and algorithms.
