Abstract: This manuscript proves the existence of a single common fixed point of two joint (A, B) generalized cyclic ϕ − abc weak nonexpansive mappings, where A and B are compact sets. The result in particular demonstrated a single fixed point of generalized cyclic ϕ − abc weak nonexpansive mappings, without the assumption of a single contracting point. Additionally, it introduces new types of generalized cyclic abc; r contraction mappings and describes the existence of a single fixed point of them in b‐metric spaces. Finally, the presented results establish a simpler convergence theorem for a sequence of generalized cyclic abc; r contraction mappings, extend, and generalize some of the previous reported results.
