- discrete mathematics - How to tell if a graph is bipartite . . .
Well, bipartite graphs are precisely the class of graphs that are 2-colorable Recall a coloring is an assignment of colors to the vertices of the graph such that no two adjacent vertices receive the same color
- Prove that all trees are bipartite - Mathematics Stack Exchange
This process continues until all vertices have been added to this isomorphic tree, call it T' We can partition the vertices of T' into two groups, A and B A will contain all vertices from even numbered rows of T', and B will contain all vertices from odd numbered rows from T' Thus, we've created a bipartition of T', so T is a bipartite graph
- prove $n$-cube is bipartite - Mathematics Stack Exchange
Hint: If a graph is bipartite, it means that you can color the vertices such that every black vertex is connected to a white vertex and vice versa Hint: Consider parity of the sum of coordinates Share
- Example for adjacency matrix of a bipartite graph
When a (simple) graph is "bipartite" it means that the edges always have an endpoint in each one of the two "parts" So if the vertices are taken in order, first from one part and then from another, the adjacency matrix will have a block matrix form: $$ A = \begin{pmatrix} 0 B \\ B^T 0 \end{pmatrix} $$
- Proof a graph is bipartite if and only if it contains no odd cycles
$\begingroup$ I don't agree with you in the textbook of Diestel, he mentiond König's theorem in page 30, and he mentiond the question of this site in page 14 he didn't say at all any similiarities between the two
- Edge-coloring of bipartite graphs - Mathematics Stack Exchange
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 bipartite graph, even if we have the same number of vertices See the figure below B and E both have degree two, but we cannot make them degree 3; Am I
- Prove that a $k$-regular bipartite graph has a perfect matching
Stack Exchange Network Stack Exchange network consists of 183 Q A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers
- How to identify bipartite graph from Adjacency matrix?
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, the graph isn't bipartite — quit and return NOT BIPARTITE Here's how to use this algorithm
