%0 Journal Article %T Viscosity Iteration Algorithm for $\varrho$-Strictly Pseudononspreading Mapping in Hilbert Space %A Bin-chao Deng %A Tong Chen and Zhi-fang Li %J Journal of Inequalities and Applications %D 2013 %I %R 10.1186/1029-242X-2013-80 %X In this paper, we discuss the strong convergence of the viscosity approximation method in Hilbert spaces, relatively to the computation of fixed points of operator in $\varrho$-strictly pseudononspreading. Under suitable conditions, some strong convergence theorems are proved. Our works improve previous results for nonspreading mappings. %U http://www.journalofinequalitiesandapplications.com/content/2013/1/80/abstract
