Abstract. We examine some structural properties of (injective and projective) tensor
products of `pspaces (projections, complemented subspaces, re exivity, isomorphisms,
etc.). We combine these results with combinatorial arguments to address the question of
primarity for these spaces and their duals.

A Banach space X is prime if every in nitedimensional complemented subspace con
tains a further subspace which is isomorphic to X. A Banach space X is said to be primary
if whenever X = Y Z, X is isomorphic to either Y or Z. The classical examples of prime
