NUMERICAL RADIUS POINTS OF L(ml∞n : l∞n )

초록

For n ≥ 2 and a real Banach space E, L(nE : E) denotes the space of all continuous n-linear mappings from E to itself. Let (Fomula Presented) where v(T) denotes the numerical radius of T. T is called numerical radius peak mapping if there is (Fomula Presented) that satisfies Nrad (Fomula Presented) . In this paper we classify Nrad(T) for every (Fomula Presented) in connection with the set of the norm attaining points of T. We also characterize all numerical radius peak mappings in (Fomula Presented) with the supremum norm. © 2022 Authors. All rights reserved.
