Objectives: This course aims to introduce students to two basic algebraic concepts, namely groups and rings. These concepts constitute an essential part of mathematical culture.

Textbook: Elements of Modern Algebra, J. Gilbert, L. Gilbert. Seventh edition. There are several copies available in the reserve section of library.

Grading: There will be two midterms on March 22 and April 26 with weights 30%. The final exam is of weight 40%. The date of the final exam will be announced later. The exam content and locations will be announced from SIS 116.

Coordinator: Ömer Küçüksakallı (

Student Assistant: Dilan Karagüler

The schedule of lectures:

  1. Gülin Ercan, Monday 10:40-11:30 in M103, Wednesday 13:40-15:30 in M103.
  2. Ömer Küçüksakallı, Monday 10:40-11:30 in M104, Wednesday 13:40-15:30 in M104.
  3. Mahmut Kuzucuoğlu, Monday 12:40-13:30 in M13, Wednesday 10:40-12:30 in M103

  5. Ferruh Özbudak, Monday 12:40-13:30 in M102, Wednesday 10:40-12:30 in M102.

NA policy: If you attend less than the %70 percent of the classes and if your two midterm scores add up to less than the %50 percent of  the total midterm score then you will not be able to take the final exam and receive the NA grade.

Conversely, if your attendance is at least %70 percent or the average of your midterm scores is at least 50, then you will be able to take final exam.

Medical reports less than 5 days will not be collected; the %70 percent attendance is to allow you for all possible minor excuses including illnesses for short terms. If you have a special situation which prevents you from coming to the lectures for a long time, you shall inform the coordinator as soon as possible.

If you are not a first year student and if you have a conflicting class, then you may attend the classes in a suitable section. You must inform the coordinator about your conflicting course so that he can change your section.

Make-up policy: Only one make-up examination will be offered. The excuse for not attending an examination must be proved with documents. The make-up examination will take place shortly after the final exam.

If you have missed both midterms, your letter grade would be NA. If you’ve missed one midterm and attended less than %70 of lectures and received a score less than 50 out of 100 from the midterm you’ve taken then your letter grade would be NA. If you receive NA, then you can not take the final exam and the makeup.
