THE NORMING SET OF A POLYNOMIAL IN P( 2 l 2
Sung Guen Kim · 2020
An element x ∈ E is called a norming point of P ∈ P(nE) if ||x|| = 1 and |(x)| ||P||. For P ∈ P(nE), we define Norm(P) = ｛x ∈ E : x is a norming point of P｝. Norm(P) is called the norming set of P. We classify Norm(P) for P ∈ P(2l2∞).
