WebA graph is a diagram of points and lines connected to the points. It has at least one line joining a set of two vertices with no vertex connecting itself. The concept of graphs in graph theory stands up on some basic terms such as point, line, vertex, edge, degree of vertices, properties of graphs, etc. WebDe nition 5. Given a graph G, the edge space Eis the free vector space over F 2 generated by E. Elements of Ecorrespond to subsets of G, and the vector addition corresponds to the symmetric di erence. De nition 6. Given a graph G, the cycle space Cis the subspace of Espanned by all the elements of Ecorresponding to cycles in G. Theorem 1.
WebGraph coloring is nothing but a simple way of labelling graph components such as vertices, edges, and regions under some constraints. In a graph, no two adjacent vertices, adjacent edges, or adjacent regions are colored with minimum number of colors. This number is called the chromatic number and the graph is called a properly colored graph. WebJul 12, 2024 · Definition: Complete Graph. A (simple) graph in which every vertex is adjacent to every other vertex, is called a complete graph. If this graph has \(n\) vertices, then it is denoted by \(K_n\). The notation \(K_n\) for a complete graph on \(n\) vertices comes from the name of Kazimierz Kuratowski, a Polish mathematician who lived from …
