Complex algebraic variety

From Wikipedia, the free encyclopedia
The Riemann sphere is one of the simplest complex algebraic varieties.

In algebraic geometry, a complex algebraic variety is an algebraic variety (in the scheme sense or otherwise) over the field of complex numbers.[1]

Chow's theorem

[edit]

Chow's theorem states that a projective complex analytic variety, i.e., a closed analytic subvariety of the complex projective space , is an algebraic variety. These are usually simply referred to as projective varieties.

Hironaka's theorem

[edit]

Let X be a complex algebraic variety. Then there is a projective resolution of singularities .[2]

Relation with similar concepts

[edit]

Despite Chow's theorem, not every complex analytic variety is a complex algebraic variety.
