WebMar 1, 2012 · The spectral distance σ (G 1 , G 2 ) between n vertex graphs G 1 and G 2 is defined by σ (G 1 , G 2 ) = n ∑ i=1 λ i (G 1 )− λ i (G 2 ) . Here we provide some initial results regarding this quantity. First, we give some general results concerning the spectral distances be- tween arbitrary graphs, and compute these ... In mathematics, computer science and especially graph theory, a distance matrix is a square matrix (two-dimensional array) containing the distances, taken pairwise, between the elements of a set. Depending upon the application involved, the distance being used to define this matrix may or may not be a metric. If there are N elements, this matrix will have size N×N. In graph-theoretic applications the elements are more often referred to as points, nodes or vertices. dj2as
