Chevalley's theorem constructible sets
WebA constructible set is a subset of Cn which is a finite union of sets of the form Z ∩ {f ≠ 0} where Z is an algebraic set. With this terminology Chevalley's theorem says that the image of a constructible set under a polynomial map Cn → Cr is constructible. Webregarding non-constructible sets, specifically, we prove that the rationals can ... vals, see for example Chevalley’s Theorem: under certain conditions the image under a polynomial map of a ...

In topology, constructible sets are a class of subsets of a topological space that have a relatively "simple" structure. They are used particularly in algebraic geometry and related fields.

WebOct 25, 2010 · By a theorem of Chevalley the image of a morphism of varieties is a constructible set. The algebraic version of this fact is usually stated as a result on "extension of specializations" or "lifting of prime ideals". We present a difference analog of this theorem. The approach is based on the philosophy that occasionally one needs to …
