Hi, I'm Declan. This is my website, which is still under construction. You can contact me here: declan.fletcher at uq.edu.au.

During Semester 1, 2025, I am organising a reading group about Galois theory.

Here is a nice formula:

\[ 1 - \frac{1}{3} + \frac{1}{5} - \frac{1}{7} + \frac{1}{9} - \frac{1}{11} + \cdots = \frac{\pi}{4}. \]
