Abstract Algebra

Course Description and Grading Breakdown

The course will be approximately devoted to three topics (more or less, depending on time and real-time choices of the instructor):

1) Around semisimple algebras.
2) Basic aspects of representation theory of finite groups.
3) Basic theory of finite groups (Group actions, Sylow theorem, solvable/nilpotent groups, semidirect products, etc).

The grading will be using weekly homework assignments (no exams).

For computational aids, you may use:


* You may use a computer or calculator while doing the homework, but may not refer to this as justification for your work.  For example, "by Mathematica" is not an acceptable justification for deriving one equation from another.  Also, since computers and calculators will not be allowed on the exams, it's best not to get too dependent on them.
