Jacobi and Laguerre quasi-orthogonal approximations and related interpolations
In this paper, we investigate Jacobi quasi-orthogonal approximation and generalized Jacobi-
Gauss-Lobatto interpolation. We also propose Laguerre quasi-orthogonal approximation
and generalized Laguerre-Gauss-Radau interpolation. A series of sharp results on these
approximations are established, which are applicable to spectral and pseudospectral
methods for mixed nonhomogeneous boundary value problems of high order. References
