一类双曲型守恒律的拟静态极限

Quasi-static limit for a hyperbolic conservation law

Stefano Marchesani, Stefano Olla, Lu Xu

摘要:

研究了具有严格凸或凹通量和不定常边界条件的一维双曲型方程的$L^\infty$熵弱解的拟静态极限.准静态轮廓随准静态方程演化,准静态方程的熵解由给定时刻边界数据对应的稳态轮廓确定。

英文摘要:

We study the quasi-static limit for the $L^\infty$ entropy weak solution of scalar one-dimensional hyperbolic equations with strictly concave or convex flux and time dependent boundary conditions. The quasi-stationary profile evolves with the quasi-static equation, whose entropy solution is determined by the stationary profile corresponding to the boundary data at a given time.
