Here are some of my notes on various topics I have thought about. Also added are some slides for non-research talks I have given.
Notes:
Supplemental notes to Mazur’s “Rational Isogenies of Prime Degree”, here.
Supplement to Section 12 from Neukirch’s “Algebraic Number Theory” on class numbers of orders in number fields, here.
Beamers:
Foray Into Galois Representations, here.
Topology on modular curves, here.
Constructible Numbers, Division Points and Class Field Theory, here.
Slides on Mazur’s “Rational Isogenies of Prime Degree”, here.
