一类对角型抛物组解的一个性质

A PROPERTY OF SOLUTIONS TO PARABOLIC EQUATION SYSTEMS IN DIAGONAL FORM

本文对一类特殊形状的对角型抛物型方程组证明：如果解在柱体Ｇ×（０，Ｔ）的抛物边界上取值为零，那么它只能是零解。

It is proved that for a special parabolic parabolic system in diagonal form if the solution u=0 on the parabolic boundary ofthe cylinder domain Q=G×(0,T).then,u is only a null solution on Q.
