spectrum of laplacian of graph _urgent
can anybody explain me what does spectrum of graph mean. i read an example. G is the graph with V as vertices and E as edges ie, G= (V, E). in example, V ={ 1 2 3} and E ={( 1,2) , (2,3)}. laplacian of graph is defined as LG, each element is l(i,j)=-1 if (i,j)belongs to E, degree if i=j, 0 otherwise. in this... 1 Aug 2010 10:29
