## Abstract

An element (x1, . . ., xn) ∈ E^{n} is called a norming point of T ∈ L(^{n}E) if kx1k = ··· = kxnk = 1 and |T(x1, . . ., xn)| = kTk, where L(^{n}E) denotes the space of all continuous n-linear forms on E. For T ∈ L(^{n}E), we define Norm(T) = n (x1, . . ., xn) ∈ E^{n} : (x1, . . ., xn) is a norming point of T ^{o} . Norm(T) is called the norming set of T. We classify Norm(T) for every T ∈ Ls(^{3}l_{1}^{2}).
