Textbook: Abstract Algebra by J.B. Fraleigh (Seventh Edition)
The aim of this course is to present the elementary theory of groups,
which is a basic tool in all abstract mathematics. We shall study the
basic properties of these abstract objects and discuss many concrete examples.
We intend to cover Chapters 14.
The final grade of this course will be based on:

twe midterm exams (40%)

one final exam (40%)
