DESCRIPTION:Alex Bearden (Tyler)\nAn operator space X is said to have the 
 weak expectation property (WEP) if the canonical inclusion of X into its s
 econd dual factors through an injective operator space. We introduce a mod
 ule version of the WEP for operator modules over completely contractive Ba
 nach algebras A. We prove many general results (for example\, characterizi
 ng the A for which A-WEP implies WEP) and also focus particularly on the c
 ases when A=L^1(G) and A=A(G) for a locally compact group G. A highlight o
 f our work is a locally compact analogue of Lance's famous result for disc
 rete groups that amenability is equivalent to WEP for the reduced C*-algeb
 ra. This is joint work with Jason Crann and Mehrdad Kalantar.
