The proof of Hall's Marriage Theorem is established, demonstrating the necessary and sufficient conditions for a complete matching exists between two subsets in a bipartite graph. The theorem states that if the number of neighbors of any subset of one partition is at least as large as the size of the subset itself, a complete matching from one partition to another is possible. Both necessary and sufficient conditions have been proven with detailed explanations along with the inductive proof strategy.

Hall's Marriage Theorem provides necessary and sufficient conditions for a complete matching in bipartite graphs.
A complete matching exists if, for every subset, the number of neighbors is at least equal to the subset size.
The proof involves both a direct proof for the necessary condition and an existential proof via induction for the sufficiency condition.
A theorem that gives necessary and sufficient conditions for the existence of a complete matching in bipartite graphs.
A graph whose vertices can be divided into two disjoint sets such that no two graph vertices within the same set are adjacent.
A matching in which every vertex of a graph is incident to exactly one edge.
