Power structures on the Grothendieck--Witt ring and the motivic Euler characteristic

Number Theory 2025-03-26 v3

Abstract

For kk a field, we construct a power structure on the Grothendieck--Witt ring of kk which has the potential to be compatible with symmetric powers of varieties and the motivic Euler characteristic. We then show this power structure is compatible with the power structure when we restrict to varieties of dimension 00.
