Number theory, Spring semester 2026
Books and references:
- We will loosely follow the book Freud-Gyarmati number theory (you can download it in hungarian legally from here).
- For the sum of four squares theorem (and Minkowski's theorem on lattices) i mostly followed this note.
- For the explicit description of the cryptographic algorithms i recommend "The handbook of applied cryptography" by Menezes and Oort (available online, sections 8.1-2 and 8.4) and for Wiener's attack on the RSA this link.
Exams:
I started to gather the exam topics here (this will be updated weekly).
