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].…”
In this paper, we introduce some new F-contractions in b-metric-like spaces and investigate some fixed point theorems for such F-contractions. Presented theorems generalize related results in the literature. An example is also given to support our main result.

“…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.…”
The aim of this paper is to define generalized (α-η)-Θ contraction and to extend the results of Jleli and Samet [M. Jleli, B. Samet, J. Inequal. Appl., 2014 (2014), 8 pages] by applying a simple condition on the function Θ. We also deduce certain fixed and periodic point results for orbitally continuous generalized Θ-contractions and certain fixed point results for integral inequalities are derived. Finally, we provide an example to show the significance of the investigation of this paper.
“…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.…”
In this paper, we introduce a new concept of cyclic (α, β)-type γ-FG-contractive mapping and we prove some fixed point theorems for such mappings in complete b-metric spaces. Suitable examples are introduced to verify the main results. As an application, we obtain sufficient conditions for the existence of solutions for nonlinear integral equation which are illustrated by an example.
