## Mathematical Notes

Here are my mathematical notes: short notes about well-known or research problems, notes from self-studying mathematical texts, and lecture notes from lectures. By "mathematics", of course theoretical computer science is included.

### Lecture Notes

**Topics in Mathematical Science VI (数理科学特論VI)** (WIP)

Lecturer: Erik Darpö, Graduate School of Mathematics, Nagoya University, Fall 2019

*A gentle introduction to module theory and homological algebra, accessible to anyone with
a basic undergraduate background in abstract algebra.*

### Short Notes

**An alternative proof of convergence for \( e^x \)**

*Proving that the exponential function converges using only the very basic facts about
infinite series.*
