We reconstruct all-genus Fan–Jarvis–Ruan–Witten invariants of a Fermat cubic Landau–
Ginzburg space (x 1 3+ x 2 3+ x 3 3:[ℂ 3∕ μ 3]→ ℂ) from genus-one primary invariants …

We introduce Virasoro operators for any Landau-Ginzburg pair (W, G) where W is a non-
degenerate quasi-homogeneous polynomial and G is a certain group of diagonal …
