量子奇异环$X^{p}+XY^{q}$

Quantum ring of singularity $X^{p}+XY^{q}$

Huijun Fan, Yefeng Shen

摘要:

本文证明了由Fan-Jarvis-Ruan-Witten理论定义的具有某个可容许对称群的拟齐次多项式$G$的量子环同构于其镜像对偶多项式$X^{p}Y+Y^{q}$的Milnor环.我们将在它们之间构造一个具体的同构。在$(p-1,q)=1$和$(p-1,q)=d>1$两种情况下,构造略有不同。还讨论了其他一些问题,包括两个Frobenius代数对之间的对应关系。

英文摘要:

In this paper, we will prove that the quantum ring of the quasi-homogeneous polynomial $X^{p}+XY^{q}(p\ge 2,q>1)$ with some admissible symmetry group $G$ defined by Fan-Jarvis-Ruan-Witten theory is isomorphic to the Milnor ring of its mirror dual polynomial $X^{p}Y+Y^{q}$. We will construct an concrete isomorphism between them. The construction is a little bit different in case $(p-1,q)=1$ and case $(p-1,q)=d>1$. Some other problems including the correspondence between the pairings of both Frobenius algebras has also been discussed.
