Numerical Methods for Computing Nonlinear . . .

With a Rayleigh quotient formulation, a local minimax method is developed to solve a class of (iso-homogeneous) nonlinear eigenpair problems for multiple solutions in Banach spaces following their instability order. The algorithm is implemented to compute (weighted) eigenpairs of the p-Laplacian. Numerical eigenfunctions are illustrated by their graphics. Several interesting phenomena have been observed and are open for further investigation. Mathematical analysis related to convergence an
