Abstract
An algebraic version of Kashiwara and Schapira's calculus of construct ible functions is used to describe local topological properties of rea l algebraic sets, including Akbulut and King's numerical conditions fo r a stratified set of dimension three to be algebraic. These propertie s, which include generalizations of the invariants module 4, 8, and 16 of Coste and Kurdyka, are defined using the link operator on the ring of constructible functions.
