Semiorthogonal decomposition conjecture for Pfaffian linear sections
Semiorthogonal decomposition conjecture for Pfaffian linear sections
Let be a vector space of dimension , let satisfy , and let be its orthogonal. Define the Pfaffian hypersurface linear section
and the dual Grassmannian linear section
Let be a categorical resolution of singularities of . Pfaffian linear-section decomposition conjecture. The derived category of coherent sheaves on has a semiorthogonal decomposition whose nontrivial component is equivalent to the derived category of ; more precisely,
This is predicted by homological projective duality for the Grassmannian and Pfaffian hypersurface. In the supplied text it is explicitly deduced from the preceding conjecture, and no independent resolution status is given.
