Abstract
Let be a Weyl number sequence. We show that for any there is a positive number such that for arbitrary Riesz operator and any the inequality
holds, where is a constant and The proof relies mainly on the relationship between absolutely 2-summing norm and multiplicity and injectivity of Weyl number.
