Description

This lecture demonstrates the existence of the direct sum of a collection of abelian groups. It provides a detailed construction of this direct sum, similar to the one seen for the vector space generated by a set. The slides cover propositions, notations, and proofs related to the uniqueness and existence of direct sums in the context of group theory.
