On properties of coincidence points of mappings between (Q1, q2 )-quasimetric spaces

In this paper, the properties of coincidence points of mappings acting between (q1, q2 )-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. © 2020 ASSA.
