Based on the technique of enriching contractive type mappings, a technique that has been used successfully in some recent papers, we introduce the concept of a saturated class of contractive mappings. We show that, from this perspective, the contract

We obtain existence and uniqueness fixed point theorems as well as approximation results for some classes of mappings defined by symmetric contractive type conditions in a convex metric space in the sense of Takahashi. By using a new approach, i.e.,

We study analytically and empirically the rate of convergence of two \(k\)-step fixed point iterative methods in the family of methods \[ x_{n+1}=T(x_{i_0+n-k+1},x_{i_1+n-k+1},\dots, x_{{i_{k-1}+n-k+1}}),\,n\geq k-1, \] where \(T\colon X^k\rightarr

We present new results on the existence and uniqueness of tripled fixed points for nonlinear mappings in partially ordered complete metric spaces that extend the results in the previous works: Berinde and Borcut, 2011, Borcut and Berinde, 2012, and B

Some fixed point theorems of Presić type for nonexpansive mappings\(f: X^k\rightarrow X\), where \(k\geq 1\) is an integer, are obtained.The main result of the paper unifies two important fixed point theorems published in the same year, 1965, the fi

We introduce the class of enriched Chatterjea contractions, obtain fixed point theorems and prove a convergence theorem for the Krasnoselskij iteration used to approximate fixed points of enriched Chatterjea mappings in Banach spaces. Then we further
