situation (2) the twisted scheme is obtained by performing birational transformations to the relative Hilbert scheme of lines. As an application we apply the results to certain complete intersections of quadrics. [3/3 of https://t.co/i48pGl2Nu8]

the quadric surface bundle are smooth and the base is a surface. We provide two proofs in situation (1) describing the scheme as the hyperbolic reduction and as a subscheme of the relative Hilbert scheme of lines, respectively. In [2/3 of https://t.co/i48p
