Add to ORKGIt has been 40 years since Whitney’s seminal paper [W1] on the structure of real algebraic varieties. This paper supplied proofs of a number of results in the folklore, but stopped short of any treatment of local properties. Some years later, Whitney [W2], [W3] returned to study local properties, distinguishing carefully between a number of different tangent cones, and relating them to stratification properties of varieties. In so doing, however, h
