Abstract
We study the recovery and approximation o f the class o f non-periodic functions in Besov space with isotropic smoothness by non-adaptive linear method.
Constructing a linear method based on the sampling value, specifically in this paper is the operator, evaluating the approximate error o f the method by the characteristic quantity
Keywords: Quasi-interpolation representation, Besov-type spaces, linear sampling method.
