Abstract

We show that super Gromov-Witten invariants can be defined and computed by methods of tropical geometry. When the target is a point, the super invariants are descendant invariants on the moduli space of curves, which can be computed tropically. When the target is a convex, toric variety XX, we describe a procedure to compute the tropical Euler class of the SUSY normal bundle Nn,β\overline{N}_{n, \beta} on M0,n(X,β)\overline{\mathcal{M}}_{0,n}(X, \beta), assuming it is locally tropicalizable in the sense of [CG], [CGM]. Then, we define the tropical, genus-0, nn-marked, super Gromov-Witten invariant of XX, and compute an example. This gives a tropical interpretation of super Gromov-Witten invariants of convex, toric varieties.
