A famous theorem of Weyl states that ifMis a compact submanifold of euclidean space, then the volumes of small tubes aboutMare given by a polynomial in the radiusr, with coefficients that are expressible as integrals of certain scalar invariants of the curvature tensor ofMwith respect to the induced metric. It is natural to interpret this phenomenon in terms of curvature measures and smooth valuations, in the sense of Alesker, canonically associated to the Riemannian structure ofM. This perspective yields a fundamental new structure in Riemannian geometry, in the form of a certain abstract module over the polynomial algebrathat reflects the behavior of Alesker multiplication. This module encodes a key piece of the array of kinematic formulas of any Riemannian manifold on which a group of isometries acts transitively on the sphere bundle. We illustrate this principle in precise terms in the case whereMis a complex space form.
