Visualisation of binomial expansion up to the 4th. To determine whether a given line bundle on a projective variety x is ample, the following numerical criteria (in terms of intersection numbers) are often the most useful. Then $i^*\mathcal{l}$ is ample on $z$, if and only if $\mathcal{l}$ is ample on $x$. Web de nition of ample:
