Math 350: Groups, Rings, and Fields
Instructor: Nathan Pflueger
This course is an introduction to abstract algebra, a central pillar of modern mathematics that concerns generalizations of the familiar addition and multiplication operations from ordinary arithmetic. The course focuses on three types of algebraic structures: groups, rings, and fields. For each structure, we study certain transformations between such structures, a library of important examples, and ways to construct one object from another. Time permitting, we will discuss several applications of abstract algebra, including a preview of public-key cryptography (a subject that I will most likely teach a semester-long course about in the spring).

Handouts and other items
- Overleaf LaTeX tutorial: this tutorial is a nice introduction for beginners. It focuses on using Overleaf, which allows you to write LaTeX documents online without installing any software.
- Overleaf Primer by Kristin Heysse (Macalester). Another tutorial on writing in LaTeX on Overleaf.
- Detexify: this is an absurdly useful tool that allows you to sketch a symbol and quickly learn the LaTeX command for it.
Problem sets will be posted here. All problem sets are due at 10pm, via Gradescope.
- Midterm 1: Friday 10/5
- Sample exams from previous semesters:
- Note: These exams should give some impression of the length and format of the exam, but the topic coverage is slightly different from previous semesters. In particular: both exams use topics from Chapter 6 (direct products), and use the notation Z(G) (for the center of a group G) that we have not used in class.
