Abstract

Let HH^\infty denote the Banach algebra of all bounded analytic functions on the open unit disc and denote by B(H)\mathscr{B}(H^\infty) the Banach space of all bounded linear operators from HH^\infty to itself. We prove that the Bishop-Phelps-Bollob\'{a}s property holds for B(H)\mathscr{B}(H^\infty). As an application to our approach, we prove that the Bishop-Phelps-Bollob\'{a}s property also holds for operator ideals of B(H)\mathscr{B}(H^\infty).

Comments

Lemma 3.1 is incorrect, so the proof of Theorem 3.2 is wrong. The same applies to the results of Section 4. However, the Urysohn-type lemma in Section 2 remains correct and appears to be a result of independent interest
