双退缩非线性抛物型方程的比较原理及其应用

A Comparison Promcole for the Doubly Nodlinear Degenerate Parabolic Equation and its Application

建立双退缩非线性抛物型方程的比较原理并用以证明一类双退缩抛物型方程初边值问题解唯一且在有限时间内耗竭．

A comparison principle for the doubly nonlinear degenerate parabolic e-quation is established and used to prove the uniqueness of the solution and the phenomenonof extinction in finite time in a special initial-boundary value problem.
