摘要
考虑具高阶耗散摩阻力的圣维南方程组的Cauchy问题,在一定的假设条件下,得到了其经典解产生奇性的结果,并对结果进行了合理的解释,验证了对于拟线性双曲方程组来说,高阶耗散并不能保证其经典解的整体存在性问题.
the Cauchy problem for Saint-Venant equations with higher order dissipative frictional resistance is studied. Under certain hypotheses, the formation of singularities for classical solution is obtained, and proper explanation of the results are given too. To some extent, the results verify that the high order dissipation can not guarantee the smoothness of classical solutions to quasilinear hyperbolic systems.
