Location: | Jones 302 |

Instructor: | Ryan Vinroot Office: Jones 130 Office Hours: M 2:30-3:30, W 3:30-4:30, Th 9-10 and 3:30-4:30, or by appointment/walk-in. |

Textbook: | Contemporary Abstract Algebra, Seventh Edition, by Joseph A. Gallian |

Grade Breakdown: | 2 Tests - 20% each, Homework - 25%, Final Exam - 35%. The grading scale will roughly be a 10 percentage point scale, so that a final score of 90% is in the A range, a score of 80% is in the B range, etc. |

Attendance Policy: | You are expected to attend all lectures. Attendance is crucial in order to succeed in the course. Especially since this is a Tues-Thurs class, missing one lecture means that you miss an awful lot of material. Any legitimate absence for a test must be discussed with me prior to the test date. |

Prerequisites: | Math 214 - Foundations of Mathematics, and Math 211 - Linear Algebra. |

Test 1 | Mar. 2 | In class | Jones 302 |

Test 2 | Apr. 6 | TBA | TBA |

Final Exam | Mon, May 10 | 9-12 | Jones 302 |

- (1/21) The first homework, listed below, is due at the beginning of class on Tues, Jan 26. The purpose of the first homework is to review crucial concepts from Math 214.
- (2/2) On Thursday, Feb. 4, I will not have office hours 9-10 AM. Please let me know if you would like to schedule another time to ask questions.
- (2/10) Due to the College closing today, I will not be holding my Wednesday afternoon office hours. Please email me if you have questions. I plan on having my regular office hours on Thursday.
- (2/23) The first midterm will be in class, on Tuesday, March 2. Here are a list of problems that are good practice problems: pgs. 91-94 #1, 5, 6, 12, 16, 27, 30, 33, 34, 44, 47.
- (3/15) My office hours on Wednesday, March 17, will be 2:30-3:30 instead of 3:30-4:30.

- (4/29) The following are a selection of review problems from the book to
prepare for the Final Exam. Please note that some of these problems might
be more involved than what you can expect on the Final Exam:

pgs. 91-94 #2, 11, 28, 35, 40

pgs. 176-177 #24, 33, 35, 44, 45, 51

pgs. 230-233 #1, 3, 7, 10, 12, 15, 28, 39

pgs. 276-278 #7, 14, 15, 19, 29. - (5/4) Here are the days and times when I will be in my office, available
for questions, before the final exam:

Wed, May 5, 2-5

Thurs, May 6, 9-12 and 2-5

Fri, May 7, 9-12 and 3:30-5

For each homework problem assigned, a complete solution with each step explained should be written up clearly and neatly. Be sure to explain your steps and reasoning for calculations as well as for proofs. Homework is due at the beginning of class on the due date of the assignment. Late homework will be marked off 20% for every day late. Homework turned in after class on the due date is considered one day late, and the day after 2 days late, and so on. Everything is easier, of course, if you turn in the homework on time!

There will be a few "Group Assignments" during the semester, other than the individual assignments. Group assignments will be completed by a group of 3 or 4 students in a collaborative effort, but only one write-up of the problems will be required. All students in the group receive the same score for the homework. The responsibility of writing up solutions should be shared. I suggest rotating this responsibility among the group members.

- There are some very useful links related to abstract algebra on the homepage of Professor Joseph Gallian, the author of the text, which is here.
- There are several opportunities for undergraduates through the William & Mary mathematics department, including research in mathematics. If you are interested, feel free to ask me or someone else in the Mathematics department about these opportunities. Information is available here.
