Strong convergence of the viscosity approximation process for the split common fixed-point problem of quasi-nonexpansive mappings

Very recently,moudafi (2011) introduced an algorithm with weak convergence for the split common fixed-point problem. in this paper,we will continue to consider the split common fixed-point problem. we discuss the strong convergence of the viscosity approximation method for solving the split common fixed-point problem for the class of quasi-nonexpansive mappings in hilbert spaces. our results improve and extend the corresponding results announced by many others. copyright © 2012 jing zhao and songnian he.
