Toward an algebraic theory of Welschinger invariants
Marc Levine
Let be a smooth del Pezzo surface over a field of characteristic . We define an invariant in the Grothendieck-Witt ring for "counting" rational curves in…

Motivic Gauß-Bonnet formulas
Marc Levine, Arpon Raksit
The apparatus of motivic stable homotopy theory provides a notion of Euler characteristic for smooth projective varieties, valued in the Grothendieck-Witt ring of the base field. P…

Motivic Euler characteristics and Witt-valued characteristic classes
Marc Levine
This paper examines a number of related questions about Euler characteristics and characteristic classes with values in Witt cohomology. We establish a motivic version of the Becke…
