关于单个守恒律有限熵解的最佳正则性估计

On optimal regularity estimates for finite-entropy solutions of scalar conservation laws

Xavier Lamy, Andrew Lorent, Guanying Peng

摘要:

我们考虑标量守恒律$u_t +a(u)_x =0$的有限熵解,即熵的产生是局部有限Radon测度的有界弱解.在通量函数$a$是严格凸的(可能退化凸)和$a''$形成加倍测度的假设下,我们得到了有限熵解的最优正则性估计的一个特征,其中包含Golse和Perthame首次使用的费用函数.

英文摘要:

We consider finite-entropy solutions of scalar conservation laws $u_t +a(u)_x =0$, that is, bounded weak solutions whose entropy productions are locally finite Radon measures. Under the assumptions that the flux function $a$ is strictly convex (with possibly degenerate convexity) and $a''$ forms a doubling measure, we obtain a characterization of finite-entropy solutions in terms of an optimal regularity estimate involving a cost function first used by Golse and Perthame.
