| Sep 8, 2010 at 1:25 | comment | added | user6976 | Ian, median spaces are not the same as M-spaces. Otherwise the answer would be positive (median spaces admitting co-compact proper isometric actions should be closely related to CAT(0)-cubical complexes). I think that an M-space does not necessarily have quadratic "isoperimetric" function, hence the answer should be in fact negative. | |
