Query: Spinor sheaves on singular quadrics   We define reflexive sheaves on a singular quadric Q that generalize the
spinor bundles on smooth quadrics, using matrix factorizations of the equation
of Q. We study the first properties of these spinor sheaves, give a
Horrocks-type criterion, and show that they are semi-stable, and indeed stable
in some cases.
