Moduli spaces of 6 x 6 skew matrices of linear forms on P^4 with a view towards intermediate Jacobians of cubic threefolds
Christian Böhning, Hans-Christian Graf von Bothmer, Lukas Buhr
It is well known that every smooth cubic threefold is the zero locus of the Pfaffian of a 6 x 6 skew-symmetric matrix of linear forms in P^4. To compactify the space of such Pfaffi…

Matrix factorizations and intermediate Jacobians of cubic threefolds
Christian Böhning, Hans-Christian Graf von Bothmer, Lukas Buhr
Results due to Druel and Beauville show that the blowup of the intermediate Jacobian of a smooth cubic threefold X in the Fano surface of lines can be identified with a moduli spac…
