quasi-projective en · ADJ

Etymology

From quasi- + projective, the sense being that projective varieties are closed subsets of projective space while quasi-projective varieties are only required to be locally closed, a strictly weaker condition. The second, scheme-theoretic sense generalizes the first.

Meanings

  1. (not-comparable, of a variety) Locally closed with respect to the Zariski topology on projective n-space; isomorphic to such a set.
  2. (not-comparable, of a scheme) Comprising an open subscheme of a projective scheme
