Welschinger--Witt invariants
Erwan Brugallé, Johannes Rau, Kirsten Wickelgren
Welschinger invariants are signed counts of real rational curves satisfying contraints. Quadratic Gromov--Witten invariants give such counts over general fields of characteristic d…
A quadratic Abramovich-Bertram formula
Erwan Brugallé, Kirsten Wickelgren
Quadratic Gromov--Witten invariants allow one to obtain an arithmetically meaningful count of curves satisfying constraints over a field without assuming that is the field…
The equivariant degree and an enriched count of rational cubics
Candace Bethea, Kirsten Wickelgren
We define the equivariant degree and local degree of a proper -equivariant map between smooth -manifolds when is a compact Lie group and prove a local to global result. W…
Quadratically enriched binomial coefficients over a finite field
Chongyao Chen, Kirsten Wickelgren
We compute an analogue of Pascal's triangle enriched in bilinear forms over a finite field. This gives an arithmetically meaningful count of the ways to choose ring homomorphis…
Motivic configurations on the line
John Igieobo, Stephen McKean, Steven Sanchez +2
For each configuration of rational points on the affine line, we define an operation on the group of unstable A1 motivic homotopy classes of endomorphisms of the projective line. W…
