The regularity of monomial ideals and their integral closures

Yijun Cui, Cheng Gong, Guangjun Zhu

Let $I$ be a monomial ideal in a polynomial ring $S = K [x_{1}, \dots, x_{n}]$ over a field $K$ with $n = 2$ or $3$ , and let $I$ be its integral closure. We will show that $\text{…

Topological and arithmetic characteristics about products of projective lines with complex tori

Jia-Li Mo, Meirav Amram, Cheng Gong

In this paper, we study non-planar degeneracies with cylindrical configurations. They could be constructed by the product $CP^{1} \times T$ of the projective plane and a com…
