Abstract: The classical Weyl principle states that the coefficients of the
volume of a tube around a compact submanifold in euclidean space are
invariants of the intrinsic metric. Using the language of valuations and
curvature measures on manifolds, they give rise to the intrinsic volumes
and Lipschitz-Killing curvature measures. In a recent joint work with
D.Faifman (Montreal) and G. Solanes (Barcelona) we extend the theory to
pseudo-riemannian manifolds and more generally to signature changing
metrics, where we prove a generalization of the Weyl principle.
