Abstract

We construct a gauged linear sigma model with two non-birational K\"alher phases which we prove to be derived equivalent, $\mathbb{L}$-equivalent, deformation equivalent and Hodge equivalent. This provides a new counterexample to the birational Torelli problem which admits a simple GLSM interpretation.

带GLSM描述的Calabi-Yau三倍的Torelli问题

我们构造了一个具有两个非二元K\“alher相的规范线性西格玛模型，我们证明了这两个相是导出等价的$\mathbb｛L｝$等价、变形等价和Hodge等价。这为二元Torelli问题提供了一个新的反例，该问题允许简单的GLSM解释。
