Higher dimensional polarized varieties with non-integral nefvalue

摘要

Let X be an n-dimensional normal projective variety with terminal, Gorenstein, Qfactorial singularities. Lt L be an ample line bundle on X. Let τbe the nefvalue of (X,L). Then we classify (X,L), describing the structure of the nefvalue morphism of (X,L), when τ satisfies n-K<τ
