Generalised graphs
WebWhat is Graph. In mathematics, a graph is a visual representation or diagram that arranges facts or values. The relationships between two or more items are commonly represented by the points on a graph. Graphs are one of the subjects covered in discrete mathematics. In discrete mathematics, notably in graph theory, a graph is a structure ... WebThe graph (formula presented) thus obtained is called the k (i)−complement of graph G with respect to the partition P. Energy of a graph G is the sum of absolute eigenvalues of G. …

In graph theory, the generalized Petersen graphs are a family of cubic graphs formed by connecting the vertices of a regular polygon to the corresponding vertices of a star polygon. They include the Petersen graph and generalize one of the ways of constructing the Petersen graph. The generalized Petersen graph family was introduced in 1950 by H. S. M.
