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 eulerize a graph?
To eulerize a graph, you need to ensure that all vertices have even degrees, as this is a requirement for a graph to have an Eulerian circuit. If any vertices have odd degrees, you can add edges between pairs of odd-degree vertices to make their degrees even. The added edges can be chosen carefully to minimize the total length of the resulting Eulerian circuit. Finally, the resulting graph will have all vertices with even degrees, allowing for an Eulerian path or circuit.
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?

What types of bar graphs are there?
pie graph, bar graph, and line graph.
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 every tree a bipartite graph?
Yes, every tree ia a bipartite graph (just see wikipedia).
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.
How can the bipartite graph algorithm be implemented using depth-first search (DFS)?
The bipartite graph algorithm can be implemented using depth-first search (DFS) by assigning colors to each vertex as it is visited. If a vertex is visited and its neighbor has the same color, then the graph is not bipartite. If all vertices can be visited without any conflicts in colors, then the graph is bipartite.
Meaning of bipartite?
"Bipartite" refers to a graph or network that can be divided into two sets of vertices such that all edges connect vertices from one set to the other, with no edges within the same set. A bipartite graph is also known as a bigraph.
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 significance of a Hamiltonian cycle in a bipartite graph and how does it impact the overall structure and connectivity of the graph?
A Hamiltonian cycle in a bipartite graph is a cycle that visits every vertex exactly once and ends at the starting vertex. It is significant because it provides a way to traverse the entire graph efficiently. Having a Hamiltonian cycle in a bipartite graph ensures that the graph is well-connected and has a strong structure, as it indicates that there is a path that visits every vertex without repeating any. This enhances the overall connectivity and accessibility of the graph, making it easier to analyze and navigate.
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.

What is the significance of perfect matching in a bipartite graph and how does it impact the overall structure and connectivity of the graph?
In a bipartite graph, a perfect matching is a set of edges that pairs each vertex in one partition with a unique vertex in the other partition. This is significant because it ensures that every vertex is connected to exactly one other vertex, maximizing the connectivity of the graph. Perfect matching plays a crucial role in determining the overall structure and connectivity of the bipartite graph, as it helps to establish relationships between different sets of vertices and can reveal important patterns or relationships within the graph.
