Notes from my studies.
Lecture notes, reading groups, and course notes in mathematics and computer science.
Reading groups
Course notes
Modern Algebra I
Abstract algebra through arithmetic and congruence in the integers, modular arithmetic, rings, polynomial rings, ideals, quotient rings, groups, normal subgroups, and quotient groups.
Read notes (PDF) →Modern Algebra II
More advanced abstract algebraic structures and concepts. Further study of group theory, including finite abelian groups and the Sylow theorems. Field extensions. Further applications of group theory, including Galois theory and geometric constructions. Arithmetic in integral domains. Additional topics such as public key cryptography or algebraic coding theory, as time permits groups.
