Generic point

A point in a topological space whose closure coincides with the whole space. A topological space having a generic point is an irreducible topological space; however, an irreducible space may have no generic point or may have many generic points. However, if the space satisfies the Kolmogorov axiom, then it can have at most one generic point. Any irreducible algebraic variety or irreducible scheme has a unique generic point. In this case the generic point is just the spectrum of the field of rational functions on the variety.

The term "generic point" is sometimes also used to denote a point in general position.

Comments

A space satisfying the Kolmogorov axiom is usually called a -space.
