“…There are several versions of this notion; the appropriate one for quasi-coherent sheaves is called the coderived category and for coherent sheaves it is the absolute derived category. The absolute derived category of locally free matrix factorizations was studied in [37]; for coherent matrix factorizations over a smooth variety, it was considered in [26]. These two absolute derived categories are equivalent for regular schemes, but can be different otherwise (as we show with an explicit counterexample).…”

“…Following [26], we will consider CDG-modules over B = (X, L, w) whose underlying graded B-modules correspond to coherent or quasi-coherent O X -modules, rather than just locally free sheaves (as in the conventional matrix factorizations). A quasicoherent CDG-module over (X, L, w) is the same thing as a pair of quasi-coherent…”
