New fixed point theorems for generalized F-contractions in complete metric spaces

Abstract: In this paper, owing to the concept of F-contraction, we define two new classes of functions M (S, T) and N(S, T), and we prove some new fixed point results for single-valued and multivalued mappings in complete metric spaces. Our results extend, generalize and unify several known results in the literature. We include an example to show that the generalization is proper.MSC: Primary 30C45; 30C10; secondary 47B38

“…(F1) F is strictly increasing, that is for all α, β ∈ (0, +∞) such that α < β, F (α) < F (β), After that, F-contraction was generalized and many fixed point theorems concerning F-contraction were investigated [3,5,6,11,16,19].…”

“…Due to its importance and simplicity, several authors have obtained many interesting extensions and generalizations of the Banach contraction principle (see [1][2][3][4][5][6][7][8][9][10][11][12][13]17] and references therein). In 2012, Samet et al [21] introduced the concepts of α-ψ-contractive and α-admissible mappings and established various fixed point theorems for such mappings defined on complete metric spaces.…”

“…In 2012, Wardowski [11] introduced the notion of an F-contraction mapping and investigated the existence of fixed points for such mappings. Afterwards, the concept of F-contraction has been generalized by many other authors, see for example [2,4]. Wardowski and Van Dung [12], as well as Piri and Kumam [9] generalized the concept of Fcontraction and proved certain fixed and common fixed point results.…”
