About Course
Abstract Group Theory.
This course will introduce abstract groups. We will start with definitions, basic properties, and constructions and cover many important theorems in basic group theory, such as Lagrange’s theorem, Cauchy’s theorem, and Sylow’s theorems. A major emphasis of the course will be to present numerous workedout examples and problems. A part of the lecture every week will be devoted to explicit calculations.
INTENDED AUDIENCE: BSc, MSc students studying mathematics.
