Ample line bundle — In algebraic geometry, a very ample line bundle is one with enough global sections to set up an embedding of its base variety or manifold M into projective space. An ample line bundle is one such that some positive power is very ample. Globally… … Wikipedia
Canonical line bundle — The canonical or tautological line bundle on a projective space appears frequently in mathematics, often in the study of characteristic classes. Note that there is possible confusion with the theory of the canonical class in algebraic geometry;… … Wikipedia
Nef line bundle — A line bundle on an algebraic variety is said to be nef (short for numerically effective or numerically eventually free ), if the degree of the restriction to any algebraic curve of the variety is non negative. In particular, every ample line… … Wikipedia
Line field — In mathematics, a line field on a manifold is a choice of a line in the tangent space to the manifold at each point, i.e. a section of the line bundle over the manifold. Line fields are of particular interest in the study of complex dynamical… … Wikipedia
