strong convergence theorem for noor iterations of afinite family of a symptotically quasi-nonexpansive type mappings in cat(0) spaces

In this paper, we study strong convergence for noor iterations of a finite family of asymptotically quasi-nonexpansive type mappings in the framework of cat(0) spaces. the said iteration scheme includes modified mann and ishikawa iterations, the three-step iteration scheme of xu and noor and the scheme of khan, domlo and fukharud- din as special cases. also, we establish some strong convergence theorems using semicompactness and condition (a). our results extend and generalize the previous works from the current existing literature.
