Title: A duality Banach spaces / operators between Lp spaces

Abstract: To a pair (X, T) of a Banach space and an operator between subspaces of Lp spaces, one associates a (possibly infinite) positive number, the norm of T between suitable subspaces of X-valued Lp spaces. I will motivate the study of this duality by examples from embeddings into Banach spaces, and I will explain a form of the bipolar theorem for this duality.
