Multiplier ideals
For a singular metric on a line bundle, Nadel, Demailly, and Yum-Tong Siu developed the concept of the multiplier ideal, which describes where the metric is most singular. There is an analog of the Kodaira vanishing theorem for such a metric, on compact or noncompact complex manifolds.[7] This led to the first effective criteria for a line bundle on a complex projective variety X of any dimension n to be very ample, that is, to have enough global sections to give an embedding of X into projective space. For example, Demailly showed in 1993 that 2K_{X}+12n^{n}L is very ample for any ample line bundle L, where addition denotes the tensor product of line bundles.
The method has inspired later improvements in the direction of the Fujita conjecture.[8]
