Fixed point theorems for cyclic self-maps involving weaker Meir-Keelerfunctions in complete metric spaces and applications

Nashine, Hemant Kumar; Romaguera Bonilla, Salvador (SpringerOpen, 2013)

We obtain fixed point theorems for cyclic self-maps on complete metric spaces involving Meir-Keeler and weaker Meir-Keeler functions, respectively. In this way, we extend several well-known fixed point theorems and, in ...
Fixed points for cyclic orbital generalized contractionson complete metric spaces

Karapınar, Erdal; Romaguera Bonilla, Salvador; Taș, Kenan (Springer Verlag (Germany), 2013-03)

We prove a fixed point theorem for cyclic orbital generalized contractions on complete metric spaces from which we deduce, among other results, generalized cyclic versions of the celebrated Boyd and Wong fixed point ...
Hu's characterization of metric completeness revisited

Romaguera Bonilla, Salvador (Dergi Park Akademik, 2022-12-30)

[EN] In this note we show the somewhat surprising fact that the proof of the `if part' of the distinguished characterizations of metric completeness due to Kirk, and Suzuki and Takahashi, respectively, can be deduced in a ...
