Abstract:

We prove that a nonempty closed and geodesically convex subset of the l∞ plane R2∞ is hyperconvex and we characterize the tight spans of arbitrary subsets of R2∞ via this property: Given any nonempty X ⊆ R2∞, a closed, geodesically convex and minimal subset Y ⊆ R2∞ containing X is isometric to the tight span T(X) of X.
