> Abstract:
> I will explain how, in a joint work with Immanuel Halupczok (Düsseldorf
> Univ.), we define in definable nonarchimedean geometry a sequence of
> invariants which is the counterpart in this context of the sequence of
> Vituskin's invariants in real geometry. For this we use the theory of
> t-stratification in its uniform version.
> We also define a notion of preorder on the ring of motivic constructible
> functions, which is compatible with motivic integration. As in the real
> case, our invariants are related to a notion of metric entropy.
