Survey of Modern Algebra

There is no official textbook. Here are the typed course notes from a previous semester. I will update them as needed as we go along. For a second opinion, I recommend the following textbooks:
  • Elements of Algebra by John Stillwell
  • Algebra by Michael Artin
  • Book of Abstract Algebra by Charles Pinter
Office Hours: Wed and Thurs at 4-5pm, via Zoom

Here is the syllabus.

There is also an optional writing credit.
