Bipartite graphs: A bipartite graph, also called a bigraph, is a set of graph vertices decomposed into two disjoint sets such that no two graph vertices within the same set are adjacent. Incidence and Degree: When a vertex vi is an end vertex of some edge ej, vi and ej are said to incident with each other.

WebJun 10, 2024 · West's Introduction to Graph Theory says. 1.1.10. Definition. A graph G is bipartite if V ( G) is the union of two disjoint (possibly empty) independent sets called partite sets of G. So under this definition, if V ( K 1) = { v }, then we let { v } be one partite set, and ∅ be the other; K 1 is bipartite. Bondy and Murty write.
