Adams-Bashforth间断有限元方法对标量非线性守恒律的先验误差估计

A priori error estimates of Adams-Bashforth discontinuous Galerkin methods for scalar nonlinear conservation laws

Charles Puelz, Beatrice Riviere

AI总结:

本文研究了Adams-Bashforth间断有限元方法在标量非线性守恒律中的收敛性,推导了两种方法的先验误差估计,时间最优,空间次优,满足CFL条件。

摘要:

本文证明了Adams-Bashforth间断有限元方法在近似标量非线性守恒律光滑解时的理论收敛性,并推导了第一阶向前欧拉间断有限元方法的先验误差估计。时间收敛率最优,空间收敛率次优,且在满足CFL条件下成立。

英文摘要:

In this paper we show theoretical convergence of a second-order Adams-Bashforth discontinuous Galerkin method for approximating smooth solutions to scalar nonlinear conservation laws with E-fluxes. A priori error estimates are also derived for a first-order forward Euler discontinuous Galerkin method. Rates are optimal in time and suboptimal in space; they are valid under a CFL condition.
