Abstract Let G be a finite group and S a finite G -monoid. A crossed G -set over S is a finite G -set equipped with a G -map into S called a weight function. A crossed Burnside ring X Ω( G , S ) is the Grothendieck ring of the category of crossed G -sets with respect to disjoint unions and tensor products. In this paper, we prove the fundamental theorem of crossed Burnside rings and an idempotent formula at characteristic 0.
