Quasi-interpolation Representation and Sampling Recovery of Multivariate Functions

  • Nguyen Manh CuongEmail author
  • Mai Xuan Thao


In this paper, we prove a multivariate generalization of the quasi-interpolation representation of functions in Besov-type spaces by B-spline series with some equivalent discrete quasi-norms. Moreover, by using this representation, we construct linear sampling methods which give the asymptotic order of optimal linear sampling methods.
