Can A Cycle Graph Be A Bipartite



Can a graph G =( V E be bipartite if it contains an odd cycle Why?

A graph G is bipartite if and only if it has no odd cycles. Proof. First, suppose that G is bipartite. Then since every subgraph of G is also bipartite, and since odd cycles are not bipartite, G cannot contain an odd cycle.

Can a bipartite graph be disconnected?

Re: can a bipartite graph have two not connected parts? A bipartite graph can be disconnected. Wikipedia says: “One often writes G=(U,V,E) to denote a bipartite graph whose partition has the parts U and V, with E denoting the edges of the graph.

What is a bipartite graph a graph which contains only one cycle?

What is a bi partite graph? Is it a graph that contains only one cycle? A graphic consists of more than three number of vortices, a graph that has an odd number of vortices and an even number of edges, or a graph that contains no cycles of odd length. The answer here is D.

Is bipartite if and only if?

A graph is bipartite if and only if every elementary cycle) consists of an even number of edges.

Which graph is a bipartite graph?

Hypercube graphs, partial cubes, and median graphs are bipartite. In these graphs, the vertices may be labeled by bitvectors, in such a way that two vertices are adjacent if and only if the corresponding bitvectors differ in a single position.

Can a complete graph ever be bipartite?

No. A complete bipartite graph is one in which the vertices can be partitioned into two parts, such that: a) Every vertex in each part is directly adjacent to a vertex in the other part.

Which of the following is not a bipartite graph?

Therefore telling us that graphs with odd cycles are not bipartite.

Is a graph without edges bipartite?

A graph with no edges and 1 or n vertices is bipartite.

Can a graph be disconnected?

An undirected graph that is not connected is called disconnected. An undirected graph G is therefore disconnected if there exist two vertices in G such that no path in G has these vertices as endpoints. A graph with just one vertex is connected. An edgeless graph with two or more vertices is disconnected.

Do bipartite graphs need to be connected?

Edit: Regarding your question on the maximum number of edges a bipartite graph on n vertices can have without being connected.
