Diamonds and super-reflexivity
Gideon Schechtman of Weizmann Institute of Science, Israel
A Banach space X is isomorphic to a uniformly convex Banach space
if and only if the diamond graphs D_n do not Lipschitz embed
into X with distortions independent of n. The same holds for
the Laakso graphs (which are doubling). Joint work with Bill Johnson.
