On the Legendre-Gauss-Lobatto points and weights. (English) Zbl 0959.65113
Finer asymptotic estimates for the Legendre-Gauss-Lobatto points and weights are presented. The sharper results have already found applications to the spectral solution of conservation laws. They are also helpful for preconditioning of Legendre spectral systems.
