In the [[mathematics|mathematical]] field of [[graph theory]], a '''bipartite graph''' (or '''bigraph''') is a [[Graph (discrete mathematics)|graph]] whose [[vertex (graph theory)|vertices]] can be divided into two [[disjoint sets|disjoint]] and [[Independent set (graph theory)|independent sets]] <math>U</math> and <math>V</math> such that every [[edge (graph theory)|edge]] connects a vertex in <math>U</math> to one in <math>V</math>. Vertex sets <math>U</math> and <math>V</math> are usually called the ''parts'' of the graph. Equivalently, a bipartite graph is a graph that does not contain any odd-length [[cycle (graph theory)|cycles]].<ref name=diestel2005graph>{{cite book|last=Diestel|first=Reinard|title=Graph Theory, Grad.

In the mathematical field of graph theory, a bipartite graph (or bigraph) is a graph whose vertices can be divided into two disjoint and independent sets {\displaystyle U}U and {\displaystyle V}V such that every edge connects a vertex in {\displaystyle U}U to one in {\displaystyle V}V. Vertex sets {\displaystyle U}U and {\displaystyle V}V are usually called the parts of the graph. Equivalently, a bipartite graph is a graph that does not contain any odd-length cycles.[1][2]
