What is the automorphism group of a complete bipartite graph?
The automorphism group of a complete bipartite graph K_n,n is (S_n x S_n) semidirect Z_2.
How do you count spanning trees in a graph?
Cayleys formula states that for a complete graph on nvertices, the number of spanning trees is n^(n-2). For a complete bipartite graph we can use the formula p^q-1 q^p-1. for the number of spanning trees. A generalization of this for any graph is Kirchhoff's theorem or Kirchhoff's matrix tree theorem. This theorem looks at the Laplacian matrix of a graph. ( you may need to look up what that is with some examples). For graphs with a small number of edges and vertices, you can find all the spanning trees and this is often quicker. There are also algorithms such as depth-first and breadth-first for finding spanning trees.
What is the name of graphs?
line graph scatter graph
What types of bar graphs are there?
pie graph, bar graph, and line graph.
How can you understand a given graph is Euler or not?
The definition of an Eulerian path is a path in a graph which visits each edge exactly once. Intuitively, think of tracing the path with a pencil without lifting the pencil's edge from the page. One definition of an Eulerian graph is that every vertex has an even degree. You can check this by counting the degrees. Please see the related link for details.
What is the automorphism group of a complete bipartite graph?
The automorphism group of a complete bipartite graph K_n,n is (S_n x S_n) semidirect Z_2.
Is tree a bipartite graph?
Yes. A graph is bipartite if it contains no odd cycles. Since a tree contains no cycles at all, it is bipartite.
Is every tree a bipartite graph?
Yes, every tree ia a bipartite graph (just see wikipedia).
The 3 types of graphs used in science?
The three kinds of graph is bar graph, line graph, and pie graph. bar graph is used to compare two or more things. A line graph is used to show changes over time. A pie graph is used to show proportions.
Show that the star graph is the only bipartiate graph which is a tree?
A star graph, call it S_k is a complete bipartite graph with one vertex in the center and k vertices around the leaves. To be a tree a graph on n vertices must be connected and have n-1 edges. We could also say it is connected and has no cycles. Now a star graph, say S_4 has 3 edges and 4 vertices and is clearly connected. It is a tree. This would be true for any S_k since they all have k vertices and k-1 edges. And Now think of K_1,k as a complete bipartite graph. We have one internal vertex and k vertices around the leaves. This gives us k+1 vertices and k edges total so it is a tree. So one way is clear. Now we would need to show that any bipartite graph other than S_1,k cannot be a tree. If we look at K_2,k which is a bipartite graph with 2 vertices on one side and k on the other,can this be a tree?
What is the plural for graphs?
The plural of graph is graphs.
What is a bigraph?
A bigraph is another term for a bipartite graph - in mathematics, a graph whose vertices can be divided into two disjoint sets.
Blank Are pictures of relationship?

What are three types of graphs scientist commonly use?
There are many graphs which while you can usually use most of them no matter what experiment you are doing that is not always true, nor is it the right use of a graph. some of the most likely graphs you will probably come across , or for that matter need to use are bar graphs, line graphs, pie graphs, and picture graphs.
What are the three different types of graphs?

What is the name of graphs?
