## Abstract

The aim of this paper is to improve some fixed point results given by I.A. Rus in
(\emph{On a fixed point theorem of Maia}, Studia Univ.
Babe\c s-Bolyai Math., 22(1977), 40-42),
(\emph{Basic problem for Maia's theorem}, Sem. on Fixed Point Theory,
Preprint 3(1981), Babe\c s-Bolyai Univ. Cluj-Napoca, 112-115) and
(\emph{Data dependence of the fixed points in a set with two metrics},
Fixed Point Theory, 8(2007), no. 1, 115-123), by applying, instead of contraction principle, some variants of Maia fixed point theorem.
