Resumen | 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 ... 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 D of self-maps of the disk all of whose powers are norm-bounded in D. |
