Description
We give some extensions of the beautiful 1968 fixed point theorem of Maia [Maia, M. G. Un’osser-vazione sulle contrazioni metriche. (Italian) Rend. Sem. Mat. Univ. Padova 40 (1968), 139–143] to three classes of enriched contractive mappings in Banach spaces: enriched contractions, Kannan enriched contractions and Ćirić-Reich-Rus contractions.
