Moduli of conic surfaces over the line
Brendan Hassett, Amanda Hernandez
We study moduli spaces and monodromy groups for surfaces fibered in conics over the projective line, with a view toward explicit presentations and arithmetic applications.

What are the odds that a conic bundle over a finite field is rational?
Amanda Hernandez
We study rationality of conic bundles over finite fields defined over the line. In particular, for a fixed number of degenerate fibers, what is the proportion of good conic bun…
