Показать описание
This lecture is part of an online course on schemes, following chapter II of the book
"Algebraic geometry" by Hartshorne.

In this lecture we give some examples of linear systems of divisors, which
are an older way of visualizing sections of an invertible sheaf by looking at the zeros of the sections.
