Relation-Theoretic Contraction Principle In Metric Spaces Using Multiplicative Contraction
Alam and Imdad have presented a novel application of the Banach contraction principle on a complete metric spaces with a binary relation. We have extended the concept of binary relation with the multiplicative contraction in a complete metric spaces.

Fixed points of multivalued nonlinear F-contractions on complete metric spaces
We introduce a new concept for multivalued maps, also called multivalued nonlinear F-contraction, and give a fixed point result. Our result is a proper generalization of some recent fixed point theorems including the famous theorem of Klim and Wardowski [

Bourbaki completeness in quasi metric spaces [PDF]
The main purpose of this paper is to define a new type of boundedness in a quasi metric space. We introduce some new notions of completeness by clustering sequences belonging to the classes larger than the classes of Cauchy sequences in some sense. We also obtain some interesting results related to the compactness.

Fixed and common fixed points for $(psi,varphi)$-weakly contractive mappings in $b$-metric spaces [PDF]
In this paper, we give a fixed point theorem for $(psi,varphi)$-weakly contractive mappings in complete $b$-metric spaces. We also give a common fixed point theorem for such mappings in complete $b$-metric spaces via altering functions. The given results

Some Extensions of Fixed Point Results over Quasi-JS-Spaces
We introduce the notion of quasi-JS-metric space. After defining the basic topological properties of quasi-JS-metric space, we investigate fixed point of certain mapping in the frame of complete quasi-JS-metric space.

A new approach on generalized quasimetric spaces induced by partial metric spaces
In this paper, we introduce the concept of generalized quasimetric spaces by a new approach, and present some examples in the partial metric spaces. Furthermore, we obtain some results on (strong) complete partial metric spaces.

In this paper, we introduce the concept of generalized α-η-ψ-φ-F -contraction type mappings where ψ is the altering distance function and φ is the ultra altering distance function.

Meir–Keeler Fixed-Point Theorems in Tripled Fuzzy Metric Spaces
In this paper, we first propose the concept of a family of quasi-G-metric spaces corresponding to the tripled fuzzy metric spaces (or G-fuzzy metric spaces). Using their properties, we give the characterization of tripled fuzzy metrics.

In this paper, we introduce the concept of generalized α-η-ψ-Geraghty contraction type mappings and prove the unique fixed point theorems for such mappings in α-η-complete metric spaces without assuming the subadditivity of ψ. We also give an example for
