An Affirmative Answer to Question 4 of Jachymski Concerning Mappings of Type
Maher Berzig
In his study of Cantor-type intersection theorems and fixed points of almost affine mappings, Jachymski \cite{Jachymski} posed four open questions. In this note, we provide an affi…
Nonlinear contraction in -suprametric spaces
Maher Berzig
We introduce the concept of -suprametric spaces and establish a fixed point result for mappings satisfying a nonlinear contraction in such spaces. The obtained result generalize…
Fixed point theorems for --contractive mappings of Meir--Keeler type and applications
Maher Berzig, Mircea-Dan Rus
In this paper, we introduce the notion of --contractive mapping of Meir--Keeler type in complete metric spaces and prove new theorems which assure the existence, uniqueness and…
Existence of positive solutions for generalized Lyapunov equations via a coupled fixed point theorem
Maher Berzig, Bessem Samet
We consider the generalized continuous-time Lyapunov equation: where is an Hermitian positive definite matrix and are arbitrary $N\ti…
