DESCRIPTION:Rufus Willett (Hawaii) \nI'll introduce the notion in the titl
 e. Motivated by Gromov’s asymptotic dimension\, we introduce a property 
 of topological dynamical systems that measures how many 'finite pieces' a 
 given action can be (locally) decomposed into. The property is a 'finite d
 imensional' version of amenability for actions\, in much the same way as a
 symptotic dimension is a 'finite dimensional version' of Yu's property A. 
 I'll give some examples\, and briefly sketch applications to controlled to
 pology\, K-theory computations\, and C*-algebra theory (without assuming a
 ny knowledge of the latter subjects).\nThis is based on joint work with Er
 ik Guentner and Guoliang Yu.
