Kemp's Theorem is a result in the field of graph theory, specifically concerning the properties of bipartite graphs. It states that a bipartite graph can be represented as a union of complete bipartite graphs if and only if it satisfies certain conditions related to its structure and connectivity. The theorem is significant because it provides a way to understand the composition of complex bipartite graphs. By breaking them down into simpler components, researchers can analyze their properties more easily, which has applications in various areas, including network theory and combinatorial optimization.
