摘要
通过引进一种新的基本方法 ,证明了C1 ,a(a >0 ) ,区域上二阶散度型椭圆方程的一个非常数弱解 ,如果其法向导数在边界的某个开子集上趋于零 ,那么该弱解在边界的每个正测度集合上不可能消失 .
It is shown that the normal derivative of a weak solution to the elliptic operators which vanishes on an open subset of the boundary of a C 1,a ,a>0, domain cannot vanish on a subset of positive surface.
