Abstract
In this paper, for a commuting pair consisting of a point-valued nonexpansive self-mapping t and a set-valued nonexpansive selfmapping
T of a hyperconvex metric space (or a CAT(0) space) X, we look for a solution to the problem of existence of z ∈ E ⊂ X
such that
d(z,y) = d(y,E) and z = t (z) ∈ T (z).
