Learners enrolled: 238   |  Exam registration: 4
ABOUT THE COURSE:
This course introduces abstract groups, starting with binary operations on a set and moving through definitions and basic properties. We will explore cyclic groups, symmetries of a triangle and square, direct products, normal subgroups, quotient groups, homomorphisms, kernels, and isomorphisms. Key theorems covered include Lagrange's theorem, Cauchy's theorem, and the three isomorphism theorems. Emphasis is placed on worked-out examples and problem-solving, with weekly lectures featuring explicit calculations to enhance understanding and practical skills. By the end of the course, students will grasp fundamental group structures, apply major theorems, and solve complex problems using group theory principles. This course is ideal for those looking to deepen their understanding of abstract algebra.

INTENDED AUDIENCE: Students/research scholar and tearcher
