convex functions and barycenters on cat(1)-spaces of small radii.
abstract:
we establish a new local convex property of cat(1)-spaces, which are metric spaces of curvature at most 1 in the sense of aleaxandrov, by showing that a function which has its origin in the study of harmonic maps is convex on any small ball of a cat(1)-space. as an application, we also discuss barycenters of probability measures on cat(1)-spaces.
