This is a directory of my pastes on Repris concerning mathematics in some way.

> **Proofs**

- [Prüfer](../prufer): proof of bijection between trees and Prüfer sequences
- [Wedderburn corollary](../wedderburn_corollary): proof that finite rings with at least two elements and no zero divisors are fields
- [Banach](../banach): proof of the Banach fixed-point theorem. This is entirely my own work, save for the tip of "recursive sequences" by my professor.
