Course content: 
This is the second semester of a course in the basic algebra of
groups, ring, fields, vector spaces, and perhaps modules over rings. Roughly speaking, the Fall semester (Math 5285) covered vector spaces, linear algebra, group theory and symmetry, doing a lot of Chapters 16 of the course text by Artin, touching lightly upon Chapters 7 and 9. In this second semester, we will study more seriously rings, fields, and perhaps modules over rings, covering some portion of Chapters 1014 of Artin's text; see below for what portion more specifically. To give some feeling for the topics, rings and fields are the keys to understanding why it is that...

Required text:  Algebra, by Michael Artin, PrenticeHall, 1991.
We expect to cover much of Chapters 1014, in this order: Ch. 10 (skip Sec. 7,8) Ch. 11 (skip Sec. 512) Ch. 13 (skip Sec. 7,8,9) Ch. 14 (skip Sec. 6) Ch. 12 (skip Sec. 8)

Homework, exams, grading: 
As with the Fall semester, there will be 5 homework assignments due usually every other week, but
I encourage collaboration on the homework, as long as each person understands the solutions, writes them up in their own words, and indicates on the homework page their collaborators. The takehome midterms and final exam are openbook, openlibrary, openweb, but in contrast to the homework on exams, no collaboration or consultation of human sources is allowed. Late homework will not be accepted. Early homework is fine, and can be left in my mailbox in the School of Math mailroom near Vincent Hall 105. Homework solutions should be wellexplained the grader is told not to give credit for an unsupported answer. Complaints about the grading should be brought to me.
