✦ Synopsis
We define and characterize Lipschitz-Killing invariants for lattices of compact sufficiently tame subsets of IR N .
Our main example are definable subsets with respect to an o-minimal system ω. We also investigate the ring M 0 (ω), which is the metric counterpart of the universal ring K 0 (ω). The Lipschitz-Killing invariants give rise to a homomorphism M 0 (ω) → IR[t], the kernel of which is the closure of {0}. Here the construction of suitable topologies plays an essential role. The results are also interpreted in terms of spherical currents.
