ItiswellknownthattheBanachcontractionprinciple[]isoneofthefundamentalresultsinnonlinearanalysisandfixedpointtheory,ingeneral.Ithasvariousapplicationsinmanybranches of applied sciences. Also, there are several extensions and generalizations of thisprinciple. For example, Kirk et al. [] obtained an extension of the Banach principle formappings satisfying cyclical contractive conditions. They also proved in [] Edelstein’s,Boyd-Wong, Geraghty and Caristy type theorem for new concept of mappings. For someother generalizations also see ([, ] and []).Following [], in [], Pacurar and Rus proved a fixed point theorem for cyclicϕ-contractions. Also, very recent, following ideas from [], Chandok and Postolache []proved a fixed point theorem for weakly Chatterjea-type cyclic contractions.However, in the present paper, we show that all these results established in [] and []are in the fact equivalent with well-known ordinary fixed point results in literature.Let us start by recalling a definition from [, ], and [].
