right inverse

The study of the left and right inverse of elements in S_n;

S_n中元素的左、右逆的研究

Some criteria of the nonexistence of right inverse for linear partial differential operator are obtained by using the point of inner support.

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 ( ) .
