The integral closedness of lattice simplices with large lattice length

Lei Song, Huanqi Wen, Zhixian Zhu

We prove that every $n$ -dimensional lattice simplex $P$ whose lattice length $L (P) \geq n - 1$ is integrally closed. As an application, we obtain a simple criterion for the projective…

On Property $N_{p}$ of line bundles on smooth projective toric varieties

Lei Song, Huanqi Wen

We establish a criterion for Property $N_{p}$ for line bundles on a class of smooth projective toric varieties. More precisely, we prove that if a smooth projective toric variety $X$ …
