Title: Optimal approximation on S-d
Author: Kushpel, A
Abstract: The asymptotic behavior of the n-widths or a wide range of sets of smooth functions on a d-dimensional sphere in L-q(S-d) is studied. Upper and lower bounds for the n-widths are established. Moreover. it is shown that these upper and lower bounds coincide for some important concrete examples. (C) 2000 Academic Press.
