A relative orientation for the moduli space of stable maps to a del Pezzo surface
Jesse Leo Kass, Marc Levine, Jake P. Solomon +1
We prove orientation results for evaluation maps of moduli spaces of rational stable maps to del Pezzo surfaces over a field, both in characteristic and in positive characteris…

A quadratically enriched count of rational curves
Jesse Leo Kass, Marc Levine, Jake P. Solomon +1
We define a quadratically enriched count of rational curves in a given divisor class passing through a collection of points on a del Pezzo surface of degree over a per…
