Title: Ax Theorem via Model Theory

Abstract: It is easy to show that if f is an injective function between two finite sets of the same size then f must be surjective. In this talk, we will show the following theorem due to Ax: if f is an injective polynomial from the complex numbers to the complex numbers then f is surjective. In order to do that, we will present some basic notions of model theory and the way they interact between them.
