Banach Center Publications 92 (2011), 91-106 MSC: Primary 46E35; Secondary 41A46. DOI: 10.4064/bc92-0-7
We prove asymptotic formulas for the behavior of Gelfand and Kolmogorov numbers of Sobolev embeddings between Besov and Triebel-Lizorkin spaces of radial distributions. Our method works also for Weyl numbers.
