摘要：
The aim of this note is to point out some errors and omissions in Theorem 2.5, Theorem 2.12 and Example 2.11 of Parvaneh et al. (J Fixed Point Theory Appl 18(4):905–925. https://doi.org/10.1007/s11784-016-0330-z, 2016), which leads to the invalidity of results and illustration. We present the corrected proofs of aforemention results.
