Algebraic Geometry Codes 1

We give a very quick reminder of classical algebraic geometry in order to define Algebraic Geometry Codes over Curves (by evaluation). The definition is a bit more complicated than ones you might have seen in order to make it possible to define the codes for the case that the support of the divisor is not disjoint from the points we want to evaluate it.
There are two kind of Algebraic Geometry Videos on my channel: Some exercises (which will suppose more knowledge about schemes and AG) and some more lecture like videos building upon another. This belongs to the first category.
