Abstract. In this paper, we introduce the concept of the $R$ -continuity and the $R$ -closedness for a pair of multivalued mappings. A new class of $(R,\alpha )$ -generalized rational multivalued contraction mappings is defined. We establish the existence of common fixed points of such mappings in the framework of $b$ -metric spaces endowed with an arbitrary binary relation $R$ . Existence of fixed and common fixed points of single valued mappings is shown in the setting of $R$ -complete $b$ -metric spaces. Several examples are constructed in support of our new results.
