Oct 13, 2015 · So I have the following graphs drawn. How can I tell whether they are bipartite? If it is bipartite, how to identify 2 disjoint non empty sets?

A regular bipartite graph has the same number of vertices in the two partions. So we need to add vertices also. I'm not sure that it is always possible to add edges to get a $\Delta$-regular …

Apr 29, 2024 · How can we prove that a graph is bipartite if and only if all of its cycles have even order? Also, does this theorem have a common name? I found it in a maths Olympiad toolbox.

Jul 24, 2024 · A bipartite graph has a unique bipartition (except for interchanging the two partite sets) if and only if it is connected. Let G be a bipartite graph. If u and v are vertices in distinct …

Oct 7, 2023 · 0 I am trying to intuitively understand why a bipartite graph in which every vertex has degree exactly $2$ is simply a cycle.

Jan 24, 2016 · Can someone explain to me with an example how to create the adjacency matrix of a bipartite graph? And why the diagonal elements of it are not zero? Thanks.

Jul 26, 2011 · I am not sure how the definition of bipartite graph fits for these graphs. If they are bipartite where is the bipartition?

Jun 7, 2020 · Of course, the definition of "bipartite" is easily generalised to graphs that are not simple, and we might want to do this in some cases: for instance if we are studying graph …

Feb 18, 2021 · Hence we obtain $k - 1$ bipartite graphs whose union consists of the complete subgraphs induced by $X$ and $Y$. The remaining edges are those of the biclique with …
