RETRACTED: Some comments concerning cyclic type contractions

摘要

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).This article has been retracted at the request of the Author and Editor in Chief due to serious errors in the data. One of the readers of this article has contacted the Editor stating that “the author claims to show that a number of fixed point papers dealing with cyclic type contractions are equivalent to their corresponding ordinary fixed point theorems. However his reasoning is fallacious. Simply put, he correctly claims that A implies B, then he draws his conclusion by asserting that, therefore, B implies A”.
