Adapt A_d axioms to other generalized spaces such as b-metric spaces
Adapt the A_d axioms to other generalized distance structures, specifically including b-metric spaces, to formulate an appropriate counterpart of A_d-contractions beyond dislocated metric spaces.

Furthermore, extending this concept to find best proximity points for non-self mappings or adapting the $\mathcal{A}_d$ axioms for other generalized spaces like b-metric spaces remain interesting open problems.
