一类退化抛物型方程的初边值问题

INITIAL-BOUNDARY VALUE PROBLEMS FOR A CLASS OF DEGENERATE PARABOLIC EQUATIONS

本文证明了由 Bertsch M.和 Ughi M.讨论的一类退化抛物型方程具 Dirichlet 边界值的初边值问题,对一大类初边值条什是不稳定的.

This paper has proved that the initial-boundary value problems for a class of degenerate parabolic equations,which were discussed by Bertsch M arid Ughi M with Dirichlet boundary values,are unstable to a great class of initial boundary values.
