We discuss an alternate method for computing the Szlenk index of an arbitrary $w^*$ compact subset of the dual of a Banach space. We discuss consequences of this method as well as offer simple, alternative proofs of a number of results already found in the literature.
On ideals of polynomials and their applications
A T(1)-Theorem in relation to a semigroup of operators and applications to new paraproducts
