【 摘 要 】
We show that the decay of approximation numbers of compact composition operators on the Dirichlet space D can be as slow as we wish. We also prove the optimality of a result of O. El-Fallah, K. Kellay, M. Shabankhah and H. Youssfi on boundedness on 7, of self-maps of the disk all of whose powers are norm-bounded in D. (C) 2015 Elsevier Inc. All rights reserved.
