A quadratically enriched count of lines on a degree 4 del Pezzo surface
Cameron Darwin
Over an algebraically closed field k, there are 16 lines on a degree 4 del Pezzo surface, but for other fields the situation is more subtle. In order to improve enumerative results…

Conics meeting eight lines over perfect fields
Cameron Darwin, Aygul Galimova, Miao Pam Gu +1
Over the complex numbers, there are 92 plane conics meeting 8 general lines in projective 3-space. Using the Euler class and local degree from motivic homotopy theory, we give an e…
