A new collocation scheme for solving hyperbolic equations of second order in a semi-infinite domain

摘要

This paper reports a new fully collocation algorithm for the numerical solution of hyperbolic partial differential equations of second order in a semi-infinite domain, using Jacobi rational Gauss-Radau collocation method.The widely applicable, efficiency, and high accuracy are the key advantages of the collocation method.The series expansion in Jacobi rational functions is the main step for solving the mentioned problems.The expansion coefficients are then determined by reducing the hyperbolic equations with their boundary and initial conditions to a system of algebraic equations for these coefficients.This system may be solved analytically or numerically in a step- by-step manner by using Newton" iterative method.Numerical results are consistent with the theoretical analysis and indicate the high accuracy and effectiveness of this algorithm.
