These are notes from a second-term abstract algebra course (Fall, 2012). I hope to cover group actions and the Sylow theorems, PIDs and UFDs, basic Galois theory, basic module theory, and the structure theorem for finitely generated modules over a PID (with applications to the structure theorem for finitely generated abelian groups and canonical forms for matrices).

The first link in each item is to a Web page; the second is to a PDF (Adobe Acrobat) file. Use the PDF if you want to print it.
