We obtain sufficient conditions for existence and uniqueness of a Chebyshev center of a nonempty bounded set in a geodesic space. We also establish conditions under which the Chebyshev center belongs to the closure of the convex shell of the mentioned set.
Keywords: Chebyshev center, geodesic space.
