440 Group Theory 2022

Welcome to Group Theory!

Contact information.

Office Hours: Office 736, Wexler Hall. Wednesdays at 2:30pm.

Office Hours of TA: (Check out MC^2)

Textbooks: We will use Armstrong's "Groups and Symmetry" extensively, but also go through Conway et al's "The symmetries of things" during class.

Exams: There will be three midterms, on Oct 6 (in class), on Oct 27 (in class), and on Nov 17 (in class) and a final (on the appropriate final exam date).

Grade breakdown: Five components, each consisting of 20 points. Midterms: 3x20 points, Final 20 points, homeworks and homework presentation 10 points+10 points=20 points. The lowest component will be dropped. (Total out of 80 points.)

Honors presentations: If you would like to do an honors project or replace an exam with a presentation, you can do a 25-minute presentation towards the end of the semester.

  • 11/29: David Costello, Matthias Mitchell.

  • 12/1: Julia Fletcher, Sangwon Lee.

Where's the Canvas? There is no canvas for this course.

Homeworks:

Homework Presentations: During each lecture, there will be one homework presentation on one problem (10-15 minutes). You may choose any problem that has not been presented yet. Sign up here.

What we'll cover: The aim for now is to cover at least the first half of Armstrong's book, and as much as possible from Conway's book. You will learn how to recognize symmetry patterns and relate them to group theory. In addition, you will learn the basic concepts of group theory, including definition of groups, subgroups, morphisms of groups, cosets, quotients, examples of groups, focusing on the geometric examples.

Week 2: Definition of groups

Absences

The conditions under which assigned work or tests can be made up, including:

o If you have to miss an exam due to religious observances/practices, please contact me beforehand.

Academic integrity

Academic honesty is expected of all students in all examinations, papers, and laboratory

work, academic transactions and records. The possible sanctions include, but are not

limited to, appropriate grade penalties, course failure (indicated on the transcript as a

grade of E), course failure due to academic dishonesty (indicated on the transcript as a

grade of XE), loss of registration privileges, disqualification and dismissal. For more

Accommodating students with disabilities

Students who feel they will need disability accommodations in this class but have not

registered with the Student Accessibility and Inclusive Learning Services Office (SAILS)

Expected classroom behavior

Classroom behavior: Under no circumstances should you allow your cell phone to ring

during class. Any disruptive behavior, which includes ringing cell phones, listening to

your mp3/iPod player, text messaging, constant talking, eating food noisily, reading a

newspaper will not be tolerated. The use of laptops (unless for note taking), cell phones,

MP3, IPOD, etc. are strictly prohibited during class.

Policy against threatening behavior

All incidents and allegations of violent or threatening conduct by an ASU student

(whether on-or off campus) must be reported to the ASU Police Department (ASU PD)

and the Office of the Dean of Students. If either office determines that the behavior

poses or has posed a serious threat to personal safety or to the welfare of the campus,

the student will not be permitted to return to campus or reside in any ASU residence hall

until an appropriate threat assessment has been completed and, if necessary,

conditions for return are imposed. ASU PD, the Office of the Dean of Students, and

other appropriate offices will coordinate the assessment in light of the relevant

circumstances.

Policy on Sexual Discrimination

Arizona State University is committed to providing an environment free of discrimination,

harassment, or retaliation for the entire university community, including all students,

faculty members, staff employees, and guests. ASU expressly prohibits discrimination ,

harassment , and retaliation by employees, students, contractors, or agents of the

university based on any protected status: race, color, religion, sex, national origin, age,

disability, veteran status, sexual orientation, gender identity, and genetic information.

As a mandated reporter, I am obligated to report any information I become aware of

regarding alleged acts of sexual discrimination, including sexual violence and dating

violence. ASU Counseling Services, https://eoss.asu.edu/counseling , is available if you

wish discuss any concerns confidentially and privately.

Copyrighted materials

A warning to students that they must refrain from uploading to any course shell,

discussion board, or website used by the course instructor or other course forum,

material that is not the student's original work, unless the students first comply with all

applicable copyright laws; faculty members reserve the right to delete materials on the

grounds of suspected copyright infringement.


Title IX is a federal law that provides that no person be excluded on the basis of sex from participation in, be denied benefits of, or be subjected to discrimination under any education program or activity. Both Title IX and university policy make clear that sexual violence and harassment based on sex is prohibited. An individual who believes they have been subjected to sexual violence or harassed on the basis of sex can seek support, including counseling and academic support, from the university. If you or someone you know has been harassed on the basis of sex or sexually assaulted, you can find information and resources at https://sexualviolenceprevention.asu.edu/faqs.
