Objectives In this paper we present some fixed point theorems for self map**s satisfying
generalized (ϕ, ψ)(ϕ, ψ)-weak contraction condition in partially ordered complete b-metric …

In 1976, Caristi fixed point theorem was proved for ordinary metric spaces. After that, it was
shown that this result is equivalent to Ekeland variational principle which has a great …

We discuss the existence of a fixed point for a self map** and its uniqueness
satisfying\(ϕ˙, η˙\)-generalized contractive condition including altering distance functions of …

In this paper, we introduce a new set Fsb of nonlinear functions. We obtain unique common
fixed point theorems for (β; F)-weak contractions under the effect of functions from Fsb …

Objectives We explore the existence of a fixed point as well as the uniqueness of a map**
in an ordered b-metric space using a generalized (̌ ψ, ̂ η)(ψ ˇ, η^)-weak contraction. In …

In this paper, two open questions on strong b-metric spaces posed by Kirk and Shahzad 11,
Chapter 12 are investigated. A counterexample is constructed to give a negative answer to …

In 1993, Czerwik [27] introduced the notion of a b-metric with a coefficient 2. This notion was
generalized later with a coefficient κ≥ 1 in [28]. In 2010 Khamsi and Hussain [58] …
