研究了一类标量对流扩散方程周期定态解的L^1 $-稳定性。利用Kruv{z}kov型熵,我们得到了所有空间维在L^2中的色散。当空间维数为1时,我们估计了解的变号次数,得到了解的L^1 $-稳定性.
The aim of this paper is to study the $L^1$-stability of periodic stationary solutions of scalar convection-diffusion equations. We obtain dispersion in $L^2$ for all space dimensions using Kruv{z}kov type entropy. And when the space dimension is one, we estimate the number of sign changes of a solution to obtain $L^1$-stability.
