Stability theorem involving comparison functions and E-distance in Hausdorff uniform spaces

Bosede A. O.

Fasciculi Mathematici

2013

Nr 51

45--52

In this paper, we establish stability result for a pair of selfmappings in Hausdorff uniform spaces by employing the notion of comparison functions as well as the concept of E-distance introduced by Aamri and El Moutawakil [1]. Our results improve and unify some of the known stability results in literature.

Some existence and uniqueness common fixed point theorems for selfmappings in uniform space

Olatinwo M. O.

Fasciculi Mathematici

2007

Nr 38

87-95

In this paper, we establish some common fixed point theorems for selfmappings in uniform space by employing both the concepts of an A—distance and an E—distance introduced by Aamri and El Moutawakil [1], We employ a contractive definition independent of those of Olatinwo [8] and Aamri and El Moutawakil [1]. Our results are also independent of those of Olatinwo [8] as well as independent of Theorems 3.1-3.3 of Aamri and El Moutawakil [1].
