“…(1) Theorem 3.1, Corollary 3.2, Corollary 3.3, and Corollary 3.4 improve and develop the corresponding results, which were obtained recently by many authors in various references, for example, see [2,3,[7][8][9][11][12][13][14][15][16][17][18]24,30]. In particular, we mention that the iterative scheme (3.1) in Theorem 3.1 of [24] is not well defined without the assumption C ± C ⊂ C on a nonempty closed convex subset C of H.…”
