研究具有一般边界条件的带退化粘性项的单个守恒律,导出了在流函数为凸的条件下其解渐近衰减到稀疏波的一个L^2-衰减估计,从而澄清了一般边界条件对衰减率的影响.
The With the general boundary data problem for scalar conservation law with degenerate viscosity is concerned. Under the condition that the flux function is convex, using L1-estimate derives a L2-decay rate of the rarefaction wave for scalar conservation law with degenerate viscosity. From this decay rate estimate, the effect of the general boundary data on the decay rate is clarified.
