Abstract

Since the collocation method approximates ordinary differential equations, partial differential equations, and integral equations in physical space, it is very easy to implement and adapt to various problems, including variable coefficient and nonlinear differential equations. In this paper, we derive a Jacobi‐Gauss‐Lobatto collocation method (J‐GL‐C) to solve numerically nonlinear time‐delayed Burgers‐type equations. The proposed technique is implemented in two successive steps. In the first one, we apply (N − 1) nodes of the Jacobi‐Gauss‐Lobatto quadrature which depend upon the two general parameters (θ, ϑ > −1), and the resulting equations together with the two‐point boundary conditions constitute a system of (N − 1) ordinary differential equations (ODEs) in time. In the second step, the implicit Runge‐Kutta method of fourth order is applied to solve a system of (N − 1) ODEs of second order in time. We present numerical results which illustrate the accuracy and flexibility of these algorithms.
