WitrynaSo, take any X that is CM, but not Gorenstein. Then ω X will be a non-locally free CM sheaf. Here is an explicit example: X = A 3 / ( x, y, z) ∼ ( − x, − y, − z) See this MO answer for a proof that ω X is not locally free. The fact that this X is CM follows from that it is a finite quotient.

WitrynaX-module is free if it is isomorphic to a direct sum of copies of O X, and it is locally free if Xcan be covered by open sets U for which Fj U is a free O Xj U-module. In that case, the rank of F on such an open set is the number of copies of the structure sheaf needed; if Xis connected, the rank of a locally free sheaf is the same everywhere.
