本文给出了反正则因子为nef的终结投射三重图的第二类陈类是伪有效的猜想的一个推论。另一方面,作为第二类Chern类的伪有效性的应用,得到了一些有效的非零结果。
We give a reduction of the conjecture that for terminal projective threefolds whose anticanonical divisors are nef, the second Chern classes are pseudo-effective. On the other hand, some effective non-vanishing results are obtained as applications of the pseudo-effectivity of the second Chern classes.
