Computing p-adic integrals using motivic integration
Karl Rökaeus
We use the theory of motivic integration in order to give a geometric explanation of the behavior of some p-adic integrals.

A version of geometric motivic integration that specializes to p-adic integration via point counting
Karl Rökaeus
We give a version of geometric motivic integration that specializes to p-adic integration via point counting. This has been done before for stable sets; we extend this to more gene…

A note on the lambda-structure on the Burnside ring
Karl Rökaeus
Let G be a finite group and let S be a G-set. The Burnside ring of G has a natural structure of a lambda-ring. However, a priori the images of S under the lambda-operations can onl…
