Grothendieck group of varieties is the free Abelian group generated by isomorphism classes of quasiprojective varieties modulo all relations of the form where is open in . Product of varieties induces a multipication on this Abelian group, making it into a ring, the Grothendieck ring of varieties.

We study the motivic Grothendieck group of algebraic varieties from the point of view of stable birational geometry. In particular, we obtain a counter-example to a conjecture of M. Kapranov on the rationality of motivic zeta-function.
An analogue in the setup of pretriangulated categories is introduced in
