Quadric surface bundles over surfaces
Asher Auel, R. Parimala, V. Suresh
Let T -> S be a finite flat morphism of degree two between regular integral schemes of dimension at most two (and with 2 invertible), having regular branch divisor D. We establish…
Exceptional collections of line bundles on projective homogeneous varieties
Alexey Ananyevskiy, Asher Auel, Skip Garibaldi +1
We construct new examples of exceptional collections of line bundles on the variety of Borel subgroups of a split semisimple linear algebraic group G of rank 2 over a field. We exh…
Cubic fourfolds containing a plane and a quintic del Pezzo surface
Asher Auel, Marcello Bernardara, Michele Bolognesi +1
We isolate a class of smooth rational cubic fourfolds X containing a plane whose associated quadric surface bundle does not have a rational section. This is equivalent to the nontr…
