Let $W$ be the quintic polynomial, let $G=\langle \mathpzc{J},e_1,e_2,e_3\rangle\cong (\mathbb{Z}/5\mathbb{Z})^4$, and let $\mathcal{W}$ denote the corresponding Calabi–Yau family.…

Let $M$ be the quintic Calabi–Yau threefold, let $W$ be the corresponding quintic polynomial, and let $(W,\langle \mathpzc{J}\rangle)$ denote its FJRW theory. Let $\mathbb{U}$ be t…
