我们考虑标量守恒律$$\Begin{Align}\Partial_tu+\mathm{div}_xF(U)=0\quad\Text{in}(0,T)\Times\mathbb{R}^d.{Align}$$∂tu+div x F(U)=0 in(0,T)×Rd的有限熵积弱解。在此基础上,在f上适当的非线性假设下,证明了u的非勒贝格点的集合至多有d个Hausdorff维。引入了这类解的拉格朗日表示的概念,从而对熵耗散度量有了新的解释。
We consider weak solutions with finite entropy production to the scalar conservation law $$\begin{aligned} \partial _t u+\mathrm {div}_x F(u)=0 \quad \text{ in } (0,T)\times \mathbb {R}^d. \end{aligned}$$ ∂ t u + div x F ( u ) = 0 in ( 0 , T ) × R d . Building on the kinetic formulation we prove under suitable nonlinearity assumption on f that the set of non Lebesgue points of u has Hausdorff dimension at most d . A notion of Lagrangian representation for this class of solutions is introduced and this allows for a new interpretation of the entropy dissipation measure.
