S. Radenovic; Sh. Sedghi; A. Gholidahneh; T. Dosenovic; J. Esfahani

Volume 05, Issue 02 , Spring 2016, , Pages 93-104

##### Abstract
In this paper is introduced a new type of generalization of metric spaces called $S_b$ metric space. For this new kind of spaces it has been proved a common fixed point theorem for four mappings which satisfy generalized contractive condition. We also present example to confirm our theorem.  Read More

##### 27. Common fixed point results on vector metric spaces

Volume 05, Issue 01 , Winter 2016, , Pages 29-39

##### Abstract
In this paper we consider the so called a vector metric space, which is a generalization of metric space, where the metric is Riesz space valued. We prove some common fixed point theorems for three mappings in this space. Obtained results extend and generalize well-known comparable results in the literature.  Read More

##### 28. Fixed Point Theorems for semi $\lambda$-subadmissible Contractions in b-Metric spaces

R. J. Shahkoohi; A. Razani

Volume 04, Issue 01 , Winter 2015, , Pages 65-85

##### Abstract
Here, a new certain class of contractive mappings in the b-metric spaces is introduced. Some fixed point theorems are proved which generalize and modify the recent results in the literature. As an application, some results in the b-metric spaces endowed with a partial ordered are proved.  Read More

##### 29. Fixed point theorems for α-ψ-ϕ-contractive integral type mappings

Volume 03, Issue 04 , Autumn 2014, , Pages 219-230

##### Abstract
In this paper, we introduce a new concept of α-ψ-ϕ-contractive integral type mappings and establish some new fixed point theorems in complete metric spaces.  Read More

Volume 03, Issue 03 , Summer 2014, , Pages 131-147

##### Abstract
In this paper, tripled coincidence points of mappings satisfying  $\psi$-contractive conditions in the framework of partially ordered $G_b$-metric spaces are obtained. Our results extend the results of Aydi et al. [H. Aydi, E. Karapinar and W. Shatanawi, Tripled fixed point results ...  Read More
