Effective Whitney stratification of real algebraic varieties

We describe new algorithms to compute Whitney stratifications of real algebraic varieties. Using either conormal or polar techniques, these algorithms stratify a complexification of a given real variety. We then show that the resulting stratification can

Smooth Maps and Real Algebraic Morphisms

, 2014
. Let X be a compact nonsingular real algebraic variety and let Y be either the blowup of Pn (R)along a linear subspace or a nonsingular hypersurface of Pm (R) × Pn (R) ofbidegree(1,1). It is proved that a C ∞ map f: X → Y can be approximated by regular
