  1. discrete mathematics - How to tell if a graph is bipartite ...

    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?

  2. Edge-coloring of bipartite graphs - Mathematics Stack Exchange

    A theorem of König says that Any bipartite graph G G has an edge-coloring with Δ(G) Δ (G) (maximal degree) colors. This document proves it on page 4 by: Proving the theorem for regular bipartite …

  3. Intuitive reason behind the fact that the definition of bipartite graph ...

    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 colourability, we …

  4. Example for adjacency matrix of a bipartite graph

    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.

  5. How to identify bipartite graph from Adjacency matrix?

    Dec 8, 2017 · If the matrix is now in the canonical form of a bipartite adjacency matrix (where the upper-left and lower-right blocks are all zero), the graph is bipartite; quit and return BIPARTITE. Otherwise, …

  6. Proof a graph is bipartite if and only if it contains no odd cycles

    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.

  7. prove $n$-cube is bipartite - Mathematics Stack Exchange

    prove n n -cube is a bipartite graph for all n ≥ 1 n ≥ 1 This is a problem in my textbook and I cannot figure it out at all and have a test on graph theory tomorrow any help would be appreciated since I …

  8. Prove that a bipartite graph has a unique bipartition if and only if it ...

    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 components, …

  9. The dimension of root polytopes for bipartite graphs $G \subseteq K_ …

    Dec 25, 2025 · Today, while reading Postnikov's work$^\color {magenta} {\star}$, I came across a question — why does the root polytope of a bipartite graph lie in an $ (m+n−2)$-dimensional affine …

  10. Complement of a bipartite graph - Mathematics Stack Exchange

    Jan 29, 2015 · I thought a constraint would be that the graphs cannot be complete, otherwise the complements would be disconnected. but, if I take a bipartite graph with 4 vertices on each side, and …
