This Week I Learned: June 10, 2022

The original treatment of generalized functions is significantly closer to non-standard analysis than I realized. Many of the definitions that I'm finding are about one or two lines removed from their hyperreal counterparts.
This week I learned about a neat proof of Dirichlet's theorem on primes in arithmetic progressions using algebraic number theory, and in particular the Frobenius automorphism of primes.
