Which Spaces can be Embedded in -type Reproducing Kernel Banach Space? A Characterization via Metric Entropy
Yiping Lu, Daozhe Lin, Qiang Du
In this paper, we establish a novel connection between the metric entropy growth and the embeddability of function spaces into reproducing kernel Hilbert/Banach spaces. Metric entr…

Nonlinear Optimal Recovery in Hilbert Spaces
Daozhe Lin, Qiang Du
This paper investigates solution strategies for nonlinear problems in Hilbert spaces, such as nonlinear partial differential equations (PDEs) in Sobolev spaces, when only finite me…
