Abstract. The main aim of the paper is to study some quantitative aspects of the stability of the weak fixed point property for nonexpansive maps in l1 (shortly, w-fpp). We focus on two complementary approaches to this topic. First, given a predual X of l1 such that the σ(l1, X)-fpp holds, we precisely establish how far, with respect to the Banach-Mazur distance, we can move from X without losi...

In this paper, we prove some coupled fixed point theorems satisfying a Meir-Keeler type contractive condition for mappings enjoying the mixed monotone property in ordered partial metric spaces.

We present an elementary axiomatisation of synthetic domain theory and show that it is sufficient to deduce the fixed point property and solve domain equations. Models of these axioms based on partial equivalence relations have received much attention, but there are also very simple sheaf models based on classical domain theory. In any case the aim of this paper is to show that an important the...

The concept of partial metric which is a generalized metric space was introduced by Matthews 1 in 1994, inwhich the distance between two identical elements needs not be zero. The existence of fixed point for contraction-type mappings on such spaces was considered by many authors 1–12 . A modified version of a Banach contraction mapping principle, more suitable to solve certain problems arising ...
