Let diam X be the diameter of X and assume diam X 2: 1. The concentration function a(X, e:) is defined for any e: > 0 by a(X,e:) = 1- inf{JL(Ae)i A DEFINITION: A family (Xn,Pn,JLn), n a Levy family if for every e: > 0, ~X Borel with JL(A) 2: ~} = 1,2, ... of metric probability spaces is called The family is called a normal Levy family with constants Cll C2, if Note that any normal Levy family is a Levy family (since we assume diamXn 2: 1). The omission of the factor diamXn in the definition of a normal Levy family comes because that way most of the examples below become Levy families with their natural metric and natural enumeration.
