It is well known that, when endowed with the Gromov-Hausdorff distance dGH, collection M of all isometry classes compact metric spaces a complete and separable space. also that (M,dGH) geodesic space, but there no structural characterization geodesics in M. In this paper we provide two characterizations We call γ:[0,1]→M Hausdorff-realizable if exists space Z containing isometric copies γ(t) fo...
