Some criteria of the nonexistence of right inverse for linear partial differential operator are obtained by using the point of inner support.
利用内支点给出了若干判定线性偏微分算子右逆不存在的方法。
Schwartz posed the problem of determining when a linear differential operator P(D) has a (continuous linear)right inverse; that is,when does there exist a cintinuous linear map R such thatP(D)R(f) = f, for all f ( ) or all f D ( ) .
