Fixed point theorems for generalized $\theta-\phi-$contraction mappings in rectangular quasi b-metric spaces

Autor: Rossafi, Mohamed, Kari, Abdelkarim

A generalized version of both rectangular metric spaces and rectangular quasi-metric spaces is known as rectangular quasi b-metric spaces (RQB-MS). In the current work, we define generalized $( \theta,\phi) $-contraction mappings and study fixed poin

Best proximity point of generalized $\theta-\phi-$proximal non-self contractions

Autor: Rossafi, Mohamed, Kari, Abdelkarim

In this manuscript, motivated and inspired by results of Best proximity point of generalized $ F $-proximal non-self contractions, we introduce the concept of generalized $\theta-\phi-$proximal contraction and prove new best proximity results for the

C-class functions and fixed points for weakly contractive mappings in rectangular b-metric spaces

Autor: Rossafi, Mohamed, Kari, Abdelkarim, Ansari, Arsalan Hojjat

In this paper, inspired by the concept of generalized weakly contractive mappings in metric spaces, we introduce C-Class function and fixed point theory for weakly contractive in the setting of rectangular $b$-metric spaces and established existence

New fixed point theorems for $(\phi, F)-$contraction on rectangular b-metric spaces

Autor: Rossafi, Mohamed, Kari, Abdelkarim

The Banach contraction principle is the most celebrated fixed point theorem, it has been generalized in various directions. In this paper, inspired by the concept of $(\phi, F)-$contraction in metric spaces, introduced by Wardowski. We present the no

Fixed point theorems in controlled rectangular metric spaces

Autor: Rossafi, Mohamed, Kari, Abdelkarim

In this paper, we introduce an extension of rectangular metric spaces called controlled rectangular metric spaces, by changing the rectangular inequality as follows: \begin{equation*} d(x, y)\leq\alpha(x, u)d(x, u)+\alpha(u, v)d(u, v)+\alpha(v, y)d(v
