On Best Error Bounds for Approximation by Piecewise Polynomial Functions.
On best simultaneous approximation.
On bivariate Hermite interpolation and the limit of certain bivariate Lagrange projectors
We give a new poised bivariate Hermite scheme and a formula for the interpolation polynomial. We show that the Hermite interpolation polynomial is the limit of bivariate Lagrange interpolation polynomials at Bos configurations on circles.
