Abstract :
In this work, we propose a high resolution Alternating Evolution Discontinuous Galerkin (AEDG) method to solve Hamilton–Jacobi equations. The construction of the AEDG method is based on an alternating evolution system of the Hamilton–Jacobi equation, following the previous work Liu et al. (2013) [31] on AE schemes for Hamilton–Jacobi equations. A semi-discrete AEDG scheme derives directly from a sampling of this system on alternating grids. Higher order accuracy is achieved by a combination of high-order polynomial approximation near each grid and a time discretization with matching accuracy. The AEDG methods have the advantage of easy formulation and implementation, and efficient computation of the solution. For the linear equation, we prove the L 2 stability of the method. Numerical experiments for a set of Hamilton–Jacobi equations are presented to demonstrate both accuracy and capacity of these AEDG schemes.
