摘要

对于一类具有实解析系数的次椭圆算子，我们提供了一个确保部分解析性结果的准则。因此，即使 "椭圆 "强唯一延续（即在某一点上无穷阶消失的同次方程解在该点附近为零）失效，零点 "传播 "的较弱形式仍然成立。

On the propagation of flatness for second order hypoelliptic operators

For a class of hypoelliptic operators with real-analytic coefficients, we provide a criterion ensuring a partial analyticity result. As a consequence, even when the “elliptic” strong unique continuation (i.e. a solution of the homogeneous equation which vanishes of infinite order at a point is zero near such a point) fails, a weaker form of “propagation” of zeroes still holds.
