Spektrum Signless-Laplace dan Spektrum Detour Graf Konjugasi dari Grup Dihedral

Kubik, 2018
Misalkan G graf berhingga yang tidak memuat loop dan sisi rangkap. Matriks keterhubungan titik A(G) dari graf G adalah matriks dengan entri aij = 1 jika vi terhubung langsung dengan vj dan aij = 0 untuk lainnya.

Signless laplacian spectral characterization of roses

Kuwait Journal of Science, 2020
A p-rose graph Γ = RG(a3, a4, . . . , as) is a graph consisting of p =a3 + a4 + · · · + as ≥ 2 cycles that all meet in one vertex, and ai (3 ≤ i ≤ s) is the number of cycles in Γ of length i.

Merging the Spectral Theories of Distance Estrada and Distance Signless Laplacian Estrada Indices of Graphs

Mathematics, 2019
Suppose that G is a simple undirected connected graph. Denote by D ( G ) the distance matrix of G and by T r ( G ) the diagonal matrix of the vertex transmissions in G, and let α ∈ [ 0 , 1 ] .

Spectra of Subdivision Vertex-Edge Join of Three Graphs

Mathematics, 2019
In this paper, we introduce a new graph operation called subdivision vertex-edge join (denoted by G 1 S ▹ ( G 2 V ∪ G 3 E ) for short), and then the adjacency spectrum, the Laplacian spectrum and the signless Laplacian spectrum of
