摘要

我们证明了方程 ut+(um)x=upu_t+(u^m)_x=-u^p 的解 um,pu_{m,p}R×(0,)\R\times (0,\infty) 中,u(x,0)=u0(x)0u(x,0)=u_0(x)\ge 0 (xRx\in\R),当 mm\to\infty (对任意 p>1p>1u0L1(R)L(R)u_0\in L^1(\R)\cap L^{\infty}(\R)) 或当 pp\to\infty (对任意 m>1m>1u0L(R)u_0\in L^{\infty}(\R)) 时的收敛性。我们还表明,一般情况下 limplimmum,plimmlimpum,p\underset{p\to\infty}\lim\underset{m\to\infty}\lim u_{m,p}\ne\underset{m\to\infty}\lim\underset{p\to\infty}\lim u_{m,p}
