Abstract
Techniques of Olin and Thomson and of Chevreau, Pearcy and Shields are used to prove the following: If T is an injective weighted shift on H with r(T)=‖T‖ then for each L ∈ (a(T), weak-*)*, there exist f, g ∈ H so that L(A)=◃Af, g▹ for all A ∈a(T). Thus the map i(A)=A is a homeomorphism from (a(T), weak-*) onto (a(T), WOT).
