Abstract
We define epsilon-stable LG quasimaps and their moduli spaces based the work of Fan--Jarvis--Ruan. We describe Favero--Kim's construction of general GLSM invariants via virtual matrix factorization; this generalizes Polischuk--Vaintrob's construction for affine LG models and Ciocan-Fontanine--Favero--Guéré--Kim--Shoemaker's construction for convex hybrid models.
