On Examples of total quasi-phi-asymptotically nonexpansive mappings. (Farrukh Mukhamedov, 14 May 2012)
The authors need to produce nontrivial exapmles for total quasi-phi-asymptotically nonexpansive mappings, which shoud not be quasi-asymptotically nonexpansive. Otherwise, results are not interesting. For some infomation, certain total asymptotically nonexpansive mappings have been
provided in [F.Mukhamedov, M.Saburov, Jour. Appl. Math. in press. (http://www.hindawi.com/journals/jam/aip/281383). Note that the provided examples are not asymptotically nonexpansive. read full comment
