Best bounds on the approximation of poly
✍ Ulrich Reif πŸ“‚ Article πŸ“… 2000 πŸ› Elsevier Science 🌐 English βš– 113 KB

We present best bounds on the deviation between univariate polynomials, tensor product polynomials, BΓ©zier triangles, univariate splines, and tensor product splines and the corresponding control polygons and nets. Both pointwise estimates and bounds on the L p -norm are given in terms of the maximum
