Abstract
In this paper, we investigate the existence and uniqueness of a fixed point of almost contractions via simulation functions in metric spaces. Moreover, some examples and an application to integral equations are given to support availability of the obtained results.

Summary
Introduction and PreliminariesIn 1922, Banach [1] initiated studies of metrical fixed points by using contractive mappings in a complete metric space. Berinde [2] proved that every almost contraction mapping defined on a complete metric space has at least one fixed point. Let ( X, d) be a complete metric space and T : X → X be a Z-contraction with respect to a function ζ satisfying certain conditions, that is, ζ (d( Tx, Ty), d( x, y)) ≥ 0 for all x, y ∈ X.
