Lecture Time and Office Hours


About the Course
MATH 3560 is a geometric introduction to the algebraic theory of groups, through the study of symmetries of planar patterns and 3–dimensional regular polyhedra. Besides studying these algebraic and geometric objects themselves, the course also provides an introduction to abstract mathematical thinking and mathematical proofs, serving as a bridge to the more advanced 4000–level courses. Abstract concepts covered include: axioms for groups; subgroups and quotient groups; isomorphisms and homomorphisms; conjugacy; group actions, orbits, and stabilizers. These are all illustrated concretely through the visual medium of geometry.
Book
The course will be based on the book "Groups and symmetry" by Mark Armstrong.
Homework
There will be a weekly homework to be handed in every Thursday during lecture time. The homework with the lower score will be dropped before computing your final grade. You can check the homework for this week by clicking the appropriate link at the top of this page or, if you are still reading this, you can just click here.
Exams
There will be a two preliminary exam. The first one will take place on Tuesday October 7th during lecture time. The second will be on Thursday november 20th, also during lecture time. You will not be allowed to bring notes to any of the exams.
Final presentation
There will be 6 final group presentations this semester. They will take place during the following days:
 Final Presentation 1, Tuesday Nov. 25th 10:10–10:40
 Final Presentation 2, Tuesday Nov. 25th 10:50–11:20
 Final Presentation 3, Tuesday Dec. 2nd 10:10–10:40

Grades
Final grades will be calculated using the formula:
20% Homework + 20% 1st Preliminary Exam + 20% 2nd Preliminary Exam + %40 Final Presentation.
Letter grades will be curved.
