G. M. Coclite, L. di Ruvo

摘要:

我们考虑Rosenau方程,其中包含非线性色散效应。证明了当扩散参数趋于零时,色散方程的解收敛到Burgers方程的间断弱解.证明依赖于导出合适的先验估计连同补偿紧性方法在L^p设置中的应用。

英文摘要:

We consider the Rosenau equation, which contains nonlinear dispersive effects. We prove that as the diffusion parameter tends to zero, the solutions of the dispersive equation converge to discontinuous weak solution of the Burgers equation. The proof relies on deriving suitable a priori estimates together with an application of the compensated compactness method in the L^p setting.
