  Equivariant curve counts valued in the Burnside Ring of a finite group

  Enumerative geometry asks for integral solutions to geometric questions, such as how many genus $g$, degree $d$ rational curves with $n$ marked points lie on a given surface. Recently, motivic and equivariant homotopy have been used to generalize classical enumerative results to non-closed fields and under the presence of a group action respectively. In this talk, we will discuss the foundational ideas of equivariant enumerative geometry and results on the count of nodal orbits in an invariant pencil of plane curves, enriched in the Burnside Ring of a finite group. Time permitting, we will discuss joint work in progress with Kirsten Wickelgen on computing Gromov-Witten invariants equivariantly.

  NOTE: There will be no pretalk this week.
