Recommended Text: Contemporary Abstract Algebra, (4th ed or higher), by Joseph Gallian
"In the broad light of day mathematicians check their equations and their proofs, leaving no stone unturned in their search for rigor. But at night, under the full moon, they dream, they float among the stars and wonder at the miracle of the heavens. They are inspired." - Michael Atiyah
Class Objectives
In this course we will continue our study of the structures that run through a number of disparate areas of mathematics, and which, when accurately defined, reveal some of the most beautiful and unifying theorems. In this course you will:
delve further into the abstract realm of Groups, Rings, and Fields - in particular you will examine extension fields, Galois Theory, Sylow Theorems, Representation Theory, and a host of other topics;
continue to develop your mathematical maturity and independence by asking good questions, forming conjectures, and conducting mathematical research;
combine creative and algebraic approaches to problem-solving, while identify underlying abstract patterns;
hone your stellar proof-writing and mathematical communication skills; and
participate in the mathematical community.
Graded Course Components*
Your grade will be based on your level of achievement in each of the following graded course components. Exact grade cut-offs will be determined at the end of the semester, with a grade of 90% and above guaranteeing an A-, 80% and above a B-, and 70% and above a C-.
10-25% Individual exams (celebrations? denouements?)**
25% Group exams**
0-15% Research Journal**
33% Problem assignments & investigations**
5% Problem presentations**
10% Perusall
2% Mathematics Colloquium Attendance
*Recognizing the uncertainty that surrounds us, relative weights are subject to change** Research journal changed to optional component replacing 2nd Individual celebration. Other weights adjusted to accommodate this change.
Individual Exams: There will be two individual exams (celebrations? denouements? an assessment by any other name is just as exciting).
Group Exams: As you know, group exams are done in groups of two or three, with each group member having a unique problem to work on. Group members proof-read each other’s work and offer suggestions. Of the 50 points possible for each group exam, 40 will be based on your work and 10 will be based on your proof-reading of team member’s exams. Each team member is allowed one page, one-sided, of notes. For more information, see the handout on Group Exams https://sites.google.com/willamette.edu/groupexaminformationpage/home.
Research Journal & Class Presentations: The best way to understand what mathematical research is like is to do it yourself. So to that end, you will be involved in your own research investigation this semester. You will record your investigations in a research journal, and be responsible for teaching the class content related to your research area. Unlike last semester, I encourage you to collaborate on these research projects - meeting with peers to discuss ideas, conduct investigations, and prep class presentations on your topic. For information on possible research topics and grading expectations, see the Research Project website https://sites.google.com/willamette.edu/algebra-ii-research-projects/home
Problem Assignments & Investigations: Throughout the semester I will assign homework sets that reinforce class concepts and provide the opportunity to apply the theorems and techniques discussed in class. I encourage you to do these homework sets collaboratively. You can either meet with peers to do the problems together, or work on the problems individually and then meet to go over your solutions and select which solutions to turn in.
Perusall & In-Class Discussions and Activities: In addition to in-class investigations, readings (including texts, podcasts, and videos) will be assigned to supplement class discussions. Your grade for this component of the course will be based on how meaningfully you engage in these activities and discussions, as based on the quality of your Perusall and in-class contributions. Perusall assess how integral your contributions are to the conversation – hence engaging with the Perusall readings early and often will increase your score.
Mathematics Colloquium Attendance: Students are expected to attend 4 of the math colloquium talks given throughout the semester. A schedule of talks can be found on the Math Department website, and linked to from the course WISE site. The goal of this attendance requirement is to introduce you to the diversity and vitality of current mathematics research, and to include you in the Math Department community.
Student Responsibility
I will do everything in my power to help you learn, but it is up to you to make the most of this experience by coming to class prepared and ready to engage in discussion. The following actions are all critical for your success in this class. If there are barriers to you doing any of the following, please let me know.
ASK QUESTIONS & THINK CRITICALLY. Throughout the course you should be asking yourself “Why are we doing this? Why does this method work? How is this related to other topics I’ve learned?” Ask questions in class, after class, during office hours, whenever! If you are confused or having problems with a certain section of the material talk to me about it. It is best to clear up confusions right away, and if you have a question, almost certainly other members of class do to. Be the brave one and speak up! The whole class will benefit from your questions.
DO THE ASSIGNMENTS. As you know, mathematics is not a spectator sport. At the same time, it can be a frustrating endeavor to engage in alone. Think of it as a team sport! I strongly encourage, and may even require, you to work with your fellow students on homework assignments.
SPEND TIME STUDYING. Willamette’s Credit Hour Policy holds that for every hour of class time there is an expectation of 3 hours of work outside of class. You should anticipate spending approximately 9 hours outside of class engaged in course-related activities. To master the content of this course you will need to invest time and effort. Set aside time for both homework and studying. A good approach would be to spend approximately 1-2 hours on reading the sections and making study notes, 3-6 hours doing the assigned problems, and 2-3 hours on your research project each week. This course is completely manageable, and you can do well in it as long as you engage from the beginning. The material builds on itself making it almost impossible to follow new material if you don’t have a firm grasp on the previously covered concepts. Furthermore, your research will be most effective if you make steady progress throughout the semester.
How to Get Unstuck
Abstract Algebra II has some of the most beautiful - and complex - definition and results you will run into in your undergraduate mathematics career. It is natural to feel a little lost or confused at times. What should you do? Discuss! Ask questions! You can start conversations on the course Discord channel, bring questions up in class, email me, arrange to meet with me, arrange to meet with other students, attend office hours, etc. We now have the capability to meet in person or virtually, so there are even more ways to talk things through with me or your classmates.
Course Policies
Inclusivity Statement: Willamette University values diversity and inclusion; we are committed to a climate of mutual respect and full participation. My goal is to create a learning environment that is effective, equitable, inclusive, and welcoming. If there are aspects of the instruction or design of this course that result in barriers to your inclusion, assessment of your work, or your achievement, please notify me as soon as possible. I will gladly honor your request to address you by your affirmed name or gender pronoun. Please advise me of this at any point in the semester so that I may make appropriate changes to my records. If I accidentally use an incorrect gender pronoun or mispronounce your name when addressing you, please let me know, in whatever manner makes you comfortable, so that I can make every effort to correct that error.
Students with disabilities are encouraged to contact the Accessible Education Services office in Smullin 155 at 503-370-6737 or Accessible-info@willamette.edu to discuss a range of options to removing barriers, including accommodations.
Missed Classes: Please make every effort to attend all classes and be an active participant in class activities and discussions. Much of your learning and understanding of new mathematical ideas will come from thinking and talking about them in class. If for some reason you are unable to attend class or turn in an assignment, please let me know as soon as possible, preferably before the missed class or assignment. I know how important athletic commitments, personal events, and religious traditions can be, and will do my best to accommodate your personal needs.
Cell Phone/Screen Policy: Unless specifically stated for class use, no phones, laptops, iPads, or other devices which take your eyes off your fellow classmates and the class discussion are allowed. Electronic devices must be turned off or silenced during class meetings. If your phone goes off, or it is clear that you are using one of these devices during class, you will be responsible for bringing treats for the entire class at the next class meeting.
Health: As a student, you may experience a range of challenges that can interfere with learning, such as strained relationships, increased anxiety, substance use, feeling down, difficulty concentrating and/or lack of motivation. These mental health concerns or stressful events may diminish your academic performance and reduce your ability to participate in daily activities. Willamette services are available and treatment does work. If you think you need help, please contact Bishop Health as soon as possible at http://willamette.edu/offices/counseling/. Crisis counseling is available 24/7 at WUTalk: 503-375-5353 and Campus Safety is available at 503-370-6911.

Academic Integrity: Students of Willamette University are members of a community that values excellence and integrity in every aspect of life. As such, we expect all community members to live up to the highest standards of personal, ethical, and moral conduct. Students are expected not to engage in any type of academic or intellectually dishonest practice and encouraged to display honesty, trust, fairness, respect, and responsibility in all they do. Plagiarism and cheating are especially offensive to the integrity of courses in which they occur and against the College community as a whole. These acts involve intellectual dishonesty, deception, and fraud, which inhibit the honest exchange of ideas. Ignorance of what constitutes plagiarism shall not be considered a valid defense. Plagiarism and cheating may be grounds for failure in the course and/or dismissal from the College. For more information, see http://willamette.edu/cla/catalog/policies/plagiarism-cheating.php. If you are unsure of what constitutes cheating, please ask me. These are the practices I expect you to follow in each of the components of the course:
on the readings, research journal, and homework assignments: You may, and are encouraged to discuss things with fellow students, and get help from your professor, textbook, notes, or calculator. However, your submitted written work should be your own or a collaboration with your assignment group. Copy/pasting sections of another's assignment or code, reading and paraphrasing another source, or providing your assignment to be copied by others, are violations of university policy. When working on a group assignment, all members of the group should contribute to producing all components of the finished product. Writing your name on work you did not contribute to in a substantive manner is a violation of university policy.
on individual tests: Throughout the course there will be individual tests and/or quizzes. Your work on these assessments should be your own, and you may not receive help from any source other than your professor (unless directed otherwise).
Intellectual Property & Privacy: Class materials and discussions including recorded lectures are for the sole purpose of educating the students enrolled in the course. The release of such information (including but not limited to directly sharing, screen capturing, or recording content) is strictly prohibited, unless the instructor states otherwise. Doing so without the permission of the instructor will be considered an Honor Code violation and may also be a violation of other state and federal laws, such as the Copyright Act. 5
DACA/Undocumented Student Advocate: Willamette is committed to supporting our DACA/Undocumented students in a variety of ways. This year, Tori Ruiz is the contact person for all DACA/undocumented students can provide those students with a number of external and internal resources that are available. Her contact information is email:truiz@willamette.edu, Office: 3rd Floor UC, Phone: 503-370-6447.
SOAR Center Offerings (Food, Clothing, and School Materials): The Students Organizing for Access to Resources (SOAR) Center strives to create equitable access to food, professional clothing, commencement regalia, and scholarly resources for WU and Willamette Academy students. The SOAR Center is located in the Putnam University Center’s third floor, across from the Harrison Conference Room. The space houses the Bearcat Pantry, Clothing Share, and First-Generation Book Drive and is maintained by committed students and advisers. Please check www.willamette.edu/go/soar for current hours of operation and email soar-center@willamette.edu for any questions or concerns.
Land Acknowledgement: We are gathered on the land of the Kalapuya, who today are represented by the Confederated Tribes of the Grand Ronde and the Confederated Tribes of Siletz Indians, whose relationship with this land continues to this day. We offer gratitude for the land itself, for those who have stewarded it for generations, and for the opportunity to study, learn, work, and be in community on this land. We acknowledge that our Universitys history, like many others, is fundamentally tied to the first colonial developments in the Willamette Valley. Finally, we respectfully acknowledge and honor past, present, and future Indigenous students of Willamette.
