Graph theory theorems
WebOct 8, 2012 · Relaxing an edge, (a concept you can find in other shortest-path algorithms as well) is trying to lower the cost of getting to a vertex by using another vertex. You are calculating the distances from a beginning vertex, say S, to all the other vertices. At some point, you have intermediate results -- current estimates. WebAlgebraic graph theory is a branch of mathematics in which algebraic methods are applied to problems about graphs. This is in contrast to geometric, ... Several theorems relate properties of the spectrum to other graph properties. As a simple example, a connected graph with diameter D will have at least D+1 distinct values in its spectrum.

WebIn the mathematical field of graph theory, Kirchhoff's theorem or Kirchhoff's matrix tree theorem named after Gustav Kirchhoff is a theorem about the number of spanning trees in a graph, showing that this number can be computed in polynomial time from the determinant of a submatrix of the Laplacian matrix of the graph; specifically, the number …

Vizing’s Theorem is the central theorem of edge-chromatic graph theory, since it provides an upper and lower bound for the chromatic index ˜0(G) of any graph G. Moreover, the upper and lower bound have a di erence of 1. That is, for all nite, simple graphs G, ( G) ˜0(G) ( G) + 1.
