Lp-valued measures without finite X-semivariation for 2 < p < ∞

Abstract

We show that for 1 < p < ∞, the property that every L p-valued vector measure has finite X-semivariation in L p(μ, X) is equivalent to the property that every continuous linear map from ℓ1 to X is p-summing. For 2 < p < ∞, we explicitly construct a
