Abstract
Given a compact oriented triangulated -manifold we find a non-trivial condition satisfied by certain labelings of the tetrahedra by elements of an arbitrary abelian group which we call angle structures. Smoothness of the manifold is used in an essential way. This is inspired by the notion of the volume of hyperbolic manifolds, which would correspond to the case when the abelian group is the multiplicative group of , but the construction here seems to be more general, in particular it only uses the abelian group structure.
