引入了包含函数及其导数端点值的广义Jacobi-Gauss-Lobatto插值,它在高阶问题的Jacobi拟谱方法中起着重要作用.我们建立了非一致加权Sobolev空间中这些插值的一些结果,这些结果可以作为数值求积分析和各种微分和积分方程数值方法的基本工具。
We introduce the generalized Jacobi-Gauss-Lobatto interpolation involving the values of functions and their derivatives at the endpoints, which play important roles in the Jacobi pseudospectral methods for high order problems. We establish some results on these interpolations in non-uniformly weighted Sobolev spaces, which serve as the basic tools in analysis of numerical quadratures and various numerical methods of differential and integral equations.
