Enumeration of Real Conics and Maximal Configurations
Erwan Brugallé, Nicolas Puignau
We use floor decompositions of tropical curves to prove that any enumerative problem concerning conics passing through projective-linear subspaces in $\RP^n$ is maximal. That is, t…

On the first Stiefel-Whitney class of moduli space for real rational stable curves in the projective space
Nicolas Puignau
Moduli space of genus zero stable maps to the projective three-space naturally carries a real structure such that the fixed locus is a moduli space for real rational spatial curves…

First Stiefel-Whitney class of real moduli spaces of stable maps to a convex surface
Nicolas Puignau
Let be a convex projective surface equipped with a real structure. The space of stable maps carries different real structures induced by $c…
