Prime Polynomial Theorem


I just wanted to point towards a nice theorem, analogous to the Prime Number Theorem, which is not talked about much:

# irreducible monic polynomials with coefficients in \mathbb{F}_q and of degree n \sim \frac{q^n}{n}, for a prime power q.

The proof of this theorem follows from Gauss’ formula:

# monic irreducible polynomialswith coefficients in \mathbb{F}_q and of degree n = \displaystyle{\frac{1}{n}\sum_{d|n}\mu\left(\frac{n}{d}\right)q^d}, by taking d=n.
