Definition

A Seifert 3-manifold is a 3-manifold which is the total space of a circle-fiber bundle (circle bundle) over a 2-dimensional orbifold. Since the circle-fibration structure may not be unique one also speaks more explicitly of Seifert-fibered manifolds.

If already the total space is a 3-orbifold, one correspondingly speaks of a Seifert orbifold etc. (e.g. Mecchia & Seppi 2020 Def. 2.6).

Fully generally one speaks of Seifert fibrations.

(Beware that there is also the un-related notion of Seifert surfaces, also considered in higher dimensions: These are coboundaries of knots.)

Beware that there is also the un-related concept of
