论文摘要
我们构建了椭圆表面对的光滑家族,并在正面或混合特征$(x,b)\ to \ mathrm {spec} r $的DVR上构建终端奇异性,因此所有足够分开的$ m> $ m> 0 $。特别是,这表明所有足够分裂的多元素内的不变性并不遵循MMP和丰富的猜想。
We construct smooth families of elliptic surface pairs with terminal singularities over a DVR of positive or mixed characteristic $(X,B)\to \mathrm{Spec}R$, such that $P_m(X_k,B_k)>P_m(X_K,B_K)$ for all sufficiently divisible $m>0$. In particular, this shows that invariance of all sufficiently divisible plurigenera does not follow from the MMP and Abundance Conjectures.
