Some results on (s-q)-graphic contraction mappings in b-metric-like spaces

Abstract

© 2019 by the authors. In this paper we consider (s-q)-graphic contraction mapping in b-metric like spaces. By using our new approach for the proof that a Picard sequence is Cauchy in the context of b-metric-like space, our results generalize, improve and complement several approaches in the existing literature. Moreover, some examples are presented here to illustrate the usability of the obtained theoretical results.
