Hypersurface
This article is licensed under the GNU Free Documentation License. It uses material from the Wikipedia article "Hypersurface".

In mathematics, a hypersurface is a kind of submanifold.

• For differential geometry usage, see glossary of differential geometry and topology.
• In algebraic geometry, a hypersurface in projective space of dimension n is an algebraic set that is purely of dimension n − 1. It is then defined by a single equation F = 0, a homogeneous polynomial in the homogeneous coordinates. (It may have singularities, so not in fact be a submanifold in the strict sense.)
