6-17 Let X coo with the norm p, 1 ≤ p ≤ co. For r > 0, consider the linear functional f, on X defined by fr (2) = ²(j) T(1) js TEX. If p = 1, then f, is continuous and fr||1 = 1. If 1 < p ≤ oo, then f, is continuous if and only if r> 1-1/p= 1/g, and then 1/q (CA) ||fr|lp=
6-14 Let M = (kij) be an infinite matrix with scalar entries. If 1 < p < 0 and 1 ≤r<∞o, define --££~) Bp.r = r/q71/r where 1/p+1/9 = 1. If pr<oo, then M defines a continuous linear map from P to l' and its operator norm is at most pr.
