Comments on “On analytic functions with generalized bounded Mocanu variation” by K.I. Noor and A. Muhammad [Appl. Math. Comput. 196 (2008) 802–811]

摘要

In this note, we show that the proof of Theorem 3.8 in the above paper is wrong since there exists several errors. Furthermore, we conjecture that the conclusion of Theorem 3.8 in the paper only holds true for the case k=2.
