论文摘要
令$ f:x \ to y $是$ f _*\ mathcal {o} _x = \ mathcal {o} _y $的正常品种的正确形态。如果$ x $是复曲的,那么$ y $是感谢您的,而$ f $是$ x $和$ y $的某些复曲面结构的复曲面形态。
Let $f:X \to Y$ be a proper morphism of normal varieties with $f_*\mathcal{O}_X = \mathcal{O}_Y$. If $X$ is toric, then $Y$ is toric and $f$ is a toric morphism for some toric structures on $X$ and $Y$.
