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 243−43 independent characteristic numbers mod 2, which generalize the Akbulut–King numbers in dimension three.
