Quadratic Segre indices
Felipe Espreafico, Stephen McKean, Sabrina Pauli
We prove that the local Euler class of a line on a degree hypersurface in projective space is given by a product of indices of Segre involutions. Segre involutions and…

Computing A1-Euler numbers with Macaulay2
Sabrina Pauli
We use Macaulay2 for several enriched counts in GW(k). First, we compute the count of lines on a general cubic surface using Macaulay2 over Fp in GW(Fp) for p a prime number and ov…
