General course information
Textbook
The textbook for the course is "Algebra" by Michael Artin (2nd edition).
Final exam
The final exam will be on Wednesday, December 9, 8:0010:00 am. It will cover
all topics studied in the course: permutations, groups, subgroups, Lagrange`s theorem, homomorphisms, modular arithmetic (Chapter 2);
orthogonal transformations, isometries, dihedral group (Chapters 5.1 and 6); orbits, stabilizers, centralizers, conjugacy classes,
normal subgroups (Chapters 2, 6 and 7.5).
Practice problems: problems , solutions .
You can also use the midterm problems for practice.
Weighed average computation:
1. Add all your paper homework grades.
2. Your weighed average is
0.4*(Final grade)+0.2*(1st midterm)+0.2*(2nd midterm)+0.2*(homework grade)/7.

Midterm 2
Midterm 2 will be on Monday, November 16. It will cover homomorphisms, isomorphisms, product groups, orthogonal transformations and isometries (including necessary linear algebra background like matrix multiplication).
Practice problems: problems
Midterm 1
Midterm 1 will be on Monday, October 19. It will cover sections 1.5 (permutations),
2.22.4 (groups, subgroups), 2.72.9 (cosets, Lagrange`s theorem, modular arithmetic).
You should know the definitions of the groups S_{n},A_{n},ℝ,
ℝ^{*},ℤ,ℤ_{n},ℤ^{*}_{n}.
Practice problems: problems
Final grade and exams
There will be two midterms on Monday, October 19 and Monday, November 16.
The Final will be on Wednesday, December 9, 8:0010:00 am.
The final grade is based on your grades for the homework, midterms and the final:

The homework should be handed in before the start of Friday lecture.
It must be legible, and written in connected sentences that explains what you are doing.
Just the answer (whether correct or not) is not enough.
ease put your name on every page and staple the pages together.
Homework should be handed in on time, late homework will not be graded.
Though it is fine to discuss the HW problems with others, you must always write up
the solutions in your own words. Copying will be penalized. Of course, in the exams
you must work on your own: no calculators, textbooks etc will be allowed.
