对于任意拟极化n-褶皱(X, L),我们发现自然数m使得多个伴随束h0(m(KX+ L))的整体截面的维数严格大于零,其中X是维数n的一个只有有理奇点的复正规Gorenstein投影变化,并且KX+ L是nef。
We find natural numbers m such that the dimensions of global sections of multiple adjoint bundles h0(m(KX+ L)) are strictly greater than zero for any quasi-polarized n-folds (X, L) for which X is a complex normal Gorenstein projective variety of dimension n with only rational singularities and KX+ L is nef.
