Title: Proving the symmetric function theorem using the chain rule
Abstract: The symmetric function theorem states that any symmetric function can be written as some function in the “elementary” symmetric functions. For example, in two variables, x^2+2xy+y^2 is symmetric, and it equals (x+y)^2, where x+y is the first elementary function in two variables. I will discuss a classical proof of this theorem, and then prove it again by brute force using the chain rule for any order derivative in any number of variables.
