Double-dual n-types over Banach spaces not containing ℓ1

Let E be a Banach space. The concept of n-type overE is introduced here, generalizing the concept of type overE introduced by Krivine and Maurey. Let E″ be the second dual of E and fix g″1,…g″n∈E″. The function τ:E×ℝn→ℝ, defined by letting τ(x,a1,…,an)=‖x+∑i=1naig″i‖ for all x∈E and all a1,…,an∈ℝ, d...
