The spectrum of the edge corona of two graphs
WebWe give complete information about the signless Laplacian spectrum of the corona of a graph G 1 and a regular graph G 2, and complete information about the signless Laplacian spectrum of the edge corona of a connected regular graph G 1 and a regular graph G 2. WebAbstract. Given two graphs G 1, with vertices 1, 2,., n and edges e 1, e 2 ,..., e m, and G 2, the edge corona G 1 {lozenge, open} G 2 of G 1 and G 2 is defined as the graph obtained by …

WebThe p660 form absorbs red light and is converted to the p73o form believed to induce a biological response. The P 7 3 0 form absorbs far-red and is converted to the inactive P 6 6 0 form. The P 7 3 0 form kept in the dark reverts to the P 6 6 0 form (Hendricks 1959). The action spectrum for photolability is seen in the lower part of Figure 9. WebAbstract In this paper, we introduce a graph operation on G 1, G 2 and G 3 and the result graph is denoted by G 1 S circ(G_2^Vcup G_3^E). Subsequently, the adjacency spectra and the Laplacian spectra of G 1 Scirc(G_2^Vcup G_3^E) are determined whenever G_1 is regular. As applications, we construct infinitely many pairs of A-cospectral graphs and L …
