Boris Haspot, Animesh Jana

AI总结:

本文证明了一维$2\times2$双曲平衡律系统在$L^\infty$小初值条件下BV解的存在性,并研究了熵解的定性行为。

摘要:

我们证明了一维空间中$2\times 2$双曲平衡律系统BV解的存在性。假设通量具有两个真正非线性的特征场。我们考虑一个一般的力,它可能依赖于时间和空间变量。为了证明存在性,我们假设初值在$L^\infty$范数下很小。此外,我们还研究了双曲平衡律系统熵解的定性行为。

英文摘要:

We prove the existence of BV solutions for $2\times 2$ system of hyperbolic balance laws in one space dimension. The flux is assumed to have two genuinely nonlinear characteristic fields. We consider a general force which may possibly depend on time and space variable as well. To prove the existence, we assume the initial data to be small in $L^\infty$. Furthermore, we also study qualitative behavior for entropy solutions to hyperbolic system of balance laws.
