Some fixed point theorems for discontinuous mappings
نویسنده
چکیده
This paper provides a fixed point theorem à la Schauder, where the mappings considered are possibly discontinuous. Our main result generalizes and unifies several well-known results. Résumé: Nous prouvons dans cet article un théorème de point fixe du type Schauder (dont un corollaire en dimension finie est le théorème de Brouwer) pour des applications qui peuvent présenter des discontinuités. Notre résultat principal généralise et unifie de nombreux résultats connus. AMS classification: 47H10

The main purpose of this research is to extend some fixed point results in orthogonal metric spaces. For this purpose, first, we investigate new mappings in this spaces. We introduce the new notions of functions. Then by using it, we define contractive mappings and then we establish and prove some fixed point theorems for such mappings in orthogonal metric spaces. Then by utilizing examples of ...

متن کاملSome common fixed point theorems for four $(psi,varphi)$-weakly contractive mappings satisfying rational expressions in ordered partial metric spaces
The aim of this paper is to prove some common fixed point theorems for four mappings satisfying $(psi,varphi)$-weak contractions involving rational expressions in ordered partial metric spaces. Our results extend, generalize and improve some well-known results in the literature. Also, we give two examples to illustrate our results.
