On Properties of Coincidence Points of Mappings between $(q_1,q_2)$-Quasimetric Spaces
Main Article Content
Abstract
In this paper, the properties of coincidence points of mappings acting between $(q_1,q_2)$-quasimetric spaces are studied. For a pair of mappings, we obtain estimates for the distance from a point to the coincidence points set and intersection of the respective graphs of the mappings. In addition, the stability of coincidence points is studied. A generalization of Lim's lemma is obtained.
