Ritz-type projectors with boundary interpolation properties and explicit spline error estimates
نویسندگان
چکیده
Abstract In this paper we construct Ritz-type projectors with boundary interpolation properties in finite dimensional subspaces of the usual Sobolev space and provide a priori error estimates for them. The abstract analysis is exemplified by considering spline spaces equip corresponding explicit constants. This complements our results recently obtained based on classical Ritz (Numer Math 144(4):889–929, 2020).

Explicit localization estimates for spline-type spaces
holds for every c ∈ `, and the functions {fk}k satisfy an spatial localization condition. In a spline-type space any function in f ∈ S has a unique expansion f = ∑ k ckfk. Moreover the coefficients are given by ck = 〈f, gk〉, where {gk}k ⊆ S is the dual basis, a set of functions characterized by the relation 〈gk, fj〉 = δk,j . These spaces provide a very natural framework for the sampling problem...

متن کاملSobolev-type Error Estimates for Interpolation by Radial Basis Functions
We generalize techniques dating back to Duchon 4] for error estimates for interpolation by thin plate splines to basis functions with positive and algebraically decaying Fourier transform. We include L p-estimates for 1 p < 2 that can also be applied to thin plate spline approximation. x1. Introduction Radial basis functions are a well-established tool for multivariate approximation problems. A...
متن کاملError Bounds for Polynomial Spline Interpolation
New upper and lower bounds for the L2 and Vo norms of derivatives of the error in polynomial spline interpolation are derived. These results improve corresponding results of Ahlberg, Nilson, and Walsh, cf. [1], and Schultz and Varga, cf. [5].
متن کاملSpline Interpolation of Functions with a Boundary Layer Component
This paper is concerned with the spline interpolation of functions with a boundary layer component. It is shown that polynomial formulas of spline interpolation for such functions lead to significant errors. We proposed nonpolynomial spline interpolation formulas, fitted to a boundary layer component. Nonsmooth and smooth on whole interval interpolants are constructed. The accuracy of construct...
