Resumen:
|
Let ? be a bounded domain in Rn and denote by id? the restriction operator from the Besov space B1+n/p pq (Rn) into the generalized Lipschitz space Lip(1,??)(?). We study the sequence of entropy numbers of this operator and prove that, up to logarithmic factors, it behaves asymptotically like ek(id?) ? k?1/p if ? > max (1 + 2/p ?1/q, 1/p). Our estimates improve previous results by Edmunds and Haroske.
