标量守恒律的振动性质

Oscillation properties of scalar conservation laws

Luis Silvestre

摘要:

我们得到了满足真非线性条件的标量守恒律解的几个新的正则性结果。我们证明了解在跳集外是连续的,跳集是余维1可求长的。我们发现,熵耗散消失远离关闭的跳跃集。我们证明了该解在$L^\infty$中以代数方式衰减为$t \to \infty$,并计算了可能的最佳衰减率。所有这些结果都是基于一个局部振荡估计,这是适当地适应德乔治的一些想法,从椭圆型方程的上下文中获得的。

英文摘要:

We obtain several new regularity results for solutions of scalar conservation laws satisfying the genuine nonlinearity condition. We prove that the solutions are continuous outside of the jump set, which is codimension one rectifiable. We show that the entropy dissipation vanishes away from the closure of the jump set. We prove that the solution decays algebraically in $L^\infty$ as $t \to \infty$ and we compute the presumably optimal decay rate. All these results are based on a local oscillation estimate which is obtained properly adapting some ideas of De Giorgi from the context of elliptic equations.
