In this paper, we introduce a new abstract structure, expanded b-metric, as an natural extension of b-metric. We also define basic topological notions in expanded bmetric to able to investigate the existence of fixed point for such mappings under various F-contractive conditions. We provide example to illustrate the results presented herein.

In this work we have considered several common fixed point results in b-metric spaces for weak compatible mappings. By applications of these results we establish some fixed point theorems in b-fuzzy metric spaces.

We show how generalized Zagreb indices $M_1^k(G)$ can be computed by using a simple graph polynomial and Stirling numbers of the second kind. In that way we explain and clarify the meaning of a triangle of numbers used to establish the same result in an earlier reference.

Altun, Ishak/0000-0002-7967-0554 WOS: 000350904800004 In this paper, we apply the concept of cyclic phi-contraction for presenting a fixed point theorem on a Hausdorff uniform space.

We prove some common fixed point results for two mappings satisfying generalized contractive condition in b-metric space. Note that b-metric of main results in this work are not necessarily continuous. So our results extend and improve several previous works. We also present one example that shows the applicability and usefulness of our results.

In this paper, we apply the concept of cyclic(φ ) -contraction for presenting a fixed point theorem on Hausdorff uniform space. Some more general results are also obtained in Hausdorff uniform space.

Altun, Ishak/0000-0002-7967-0554 WOS: 000262318800013 In this paper we prove a fixed point theorem for fuzzy mappings over a complete metric space.

In this paper, we establish a common fixed point theorem in complete fuzzy metric spaces which generalizes some results in [3].

We give some new definitions of -metric spaces and we prove a common fixed point theorem for a class of mappings under the condition of weakly commuting mappings in complete -metric spaces. We get some improved versions of several fixed point theorems in complete -metric spaces.

In this paper , we obtain two general common coupled fixed point theorems for maps in fuzzy metric spaces.
