Let $X_{\zeta_{+}}$ be any Calabi–Yau threefold constructed by the GLSM flop procedure, with coordinates $z_{1},\ldots,z_{r}$ and divisors $\widehat D_{\alpha-1,\alpha}$. Assume th…

Consider the extended GLSM in the positive phase $\zeta>0$, with GLSM $I$-function $I^+_w(q,z)$ and GLSM small $J$-function $J^+_w(Q,z)$. Let $I^{\mathrm{CY}}_0(q,z)$ and…

In a GLSM, let hemisphere partition functions be the explicit analytic functions constructed by Hori and Romo, and let their power series expansions be compared with central charge…
