| Mar 23, 2013 at 7:17 | comment | added | m07kl | Yu's property A is only defined for discrete metric space. Higson proved that they are the same for discrete groups, but I only interest in non-doscrete cases. see math.psu.edu/higson/math/Papers_files/… | |

| Mar 23, 2013 at 2:24 | comment | added | user6976 | What is a connection between this property and G. Yu's property A? | |
