Isomorphism Theorems: Quotients of Group

This lecture covers the formulation and proof of the famous isomorphism theorems for quotient groups. The first theorem states that every homomorphism induces an isomorphism from the quotient of its domain by its kernel to its image. The second theorem deals with groups and subgroups, while the third theorem focuses on groups and normal subgroups. The lecture also explains the concept of surjective homomorphisms and the calculation of kernels.
