On the power of standard information for tractability for $L_{2}$ -approximation in the average case setting

Wanting Lu, Heping Wang

We study multivariate approximation in the average case setting with the error measured in the weighted $L_{2}$ norm. We consider algorithms that use standard information $Λ^{\rm std…

On the power of standard information for tractability for $L_{2}$ -approximation in the randomized setting

Wanting Lu, Heping Wang

We study approximation of multivariate functions from a separable Hilbert space in the randomized setting with the error measured in the weighted $L_{2}$ norm. We consider algorithms…

Approximation and quadrature by weighted least squares polynomials on the sphere

Wanting Lu, Heping Wang

Given a sequence of Marcinkiewicz-Zygmund inequalities in $L_{2}$ on a usual compact space $M$ , Gröchenig introduced the weighted least squares polynomials and the least squ…
