Abstract: This paper discusses spectral and spectral element methods with Legendre‐Gauss‐Lobatto nodal basis for general 2nd‐order elliptic eigenvalue problems. The special work of this paper is as follows. (1) We prove a priori and a posteriori error estimates for spectral and spectral element methods. (2) We compare between spectral methods, spectral element methods, finite element methods and their derived p‐version, h‐version, and hp‐version methods from accuracy, degree of freedom, and stability and verify that spectral methods and spectral element methods are highly efficient computational methods.
