摘要
In dimension 2 there is a very useful criterion, due to Miles Reid, giving a necessary and sufficient condition for an adjoint linear system on a nonsingular complex projective surface X to be free at a point p is an element of X, in terms of the coherent cohomology of certain divisors on the blowup of X at p. In this note we extend Miles Reid's result to higher dimensions.
