In this paper, we study optimal recovery (reconstruction) of functions on the sphere in the average case setting. We obtain the asymptotic orders of average sampling numbers of a Sobolev space on the sphere with a G...

We consider Jackson inequality in L^2 (B^d×T, Wκ,μ^B (x)), where the weight function Wκ,μ^B (X) is defined on the ball B^d and related to reflection group, and obtain the sharp Jackson inequalityEn-1,m-1(f...

We investigate the asymptotic behavior of the entropy numbers of Besov classes BBΩp,θ(Sd 1)of generalized smoothness on the sphere inL q(Sd 1)for 1≤p,q,θ≤∞,and get their asymptotic orders.We also obtain the ...
