Abstract

Operators on the ring of algebraically constructible functions are used to compute local obstructions for a four-dimensional semialgebraic set to be homeomorphic to a real algebraic set. The link operator and arithmetic operators yield 243432^{43}-43 independent characteristic numbers mod 2, which generalize the Akbulut-King numbers in dimension three.
