Part of the Graduate Texts in Mathematics book series (GTM, volume 19)


Consider first the simple unilateral shift U. Let 〈ξ0, ξ1, ξ2, ⋯〉 be a sequence of complex numbers such that
$$ \mathop {\lim }\limits_k \frac{1}{{{{\left| {{\xi _k}} \right|}^2}}}\sum\limits_{n = 1}^\infty {{{\left| {{\xi _{n + k}}} \right|}^2}} = 0. $$
