Resumen
Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Estimates of Kolmogorov and linear n-widths of Besov classes on compact globally symmetric spaces of rank 1 (i.e., on S(d), P(d)(R), P(d)(C), P(d)(H), P(16)(Cay)) are established. It is shown that these estimates have sharp orders in different important cases. A new characterisation of Besov spaces is also given. (C) 2009 WILEY-VCH Verlag GmbH & Co.
