Entropy numbers of weighted Sobolev classes on the unit sphere
Heping Wang, Wang Kai
We obtain the asymptotic orders of entropy numbers of Sobolev classes on the unit sphere with Dunkl weight which associates with the finite reflection group. Moreover, the asymptot…
Strong equivalences of approximation numbers and tractability of weighted anisotropic Sobolev embeddings
JiDong Hao, Heping Wang
In this paper, we study multivariate approximation defined over weighted anisotropic Sobolev spaces which depend on two sequences and ${\bf b}=\{b_j\}_{j…
Average case tractability of additive random fields with Korobov kernels
Jia Chen, Heping Wang
We investigate average case tractability of approximation of additive random fields with marginal random processes corresponding to the Korobov kernels for the non-homogeneous case…
Tractability of non-homogeneous tensor product problems in the worst case setting
Rong Guo, Heping Wang
We study multivariate linear tensor product problems with some special properties in the worst case setting. We consider algorithms that use finitely many continuous linear functio…
