Abstract: In this paper, we introduce two new classes of cyclic-type mappings, namely, co-cyclic mappings and sub-cyclic mappings, defined on the union of two subsets of a metric space. Under suitable Jungck-type contractive conditions and compatibility assumptions, we establish unique common fixed point theorems for these mappings in complete metric spaces. The proofs are based on the construction of appropriate sequences, the associated contractive conditions, and the completeness of the underlying metric space. Examples are provided to illustrate the proposed concepts and to demonstrate the applicability of the main results. Finally, some open questions and possible directions for further research concerning co-cyclic and sub-cyclic mappings are presented.
