Bivariate interpolation at Xu points: results, extensions and applications
Electronic transactions on numerical analysis, Tome 25 (2006), pp. 1-16
In a recent paper, Y. Xu proposed a set of Chebyshev-like points for polynomial interpolation on the square . We have recently proved that the Lebesgue constant of these points grows like of the
