ENERGY AND LAPLACIAN SPECTRUM OF C 4 C 8 (S) NANOTORI AND NANOTUBE [PDF]
The spectrum of a finite graph is by definition the spectrum of the adjacency matrix, that is, its set of eigenvalues together with their multiplicities. The sum of the absolutes of these eigenvalues is the energy of graph.

On the Laplacian Spectrum of (α, ω) -Graphs
We study the Laplacian spectrum of (α, ω)-graphs which play an important role in the theory of perfect graphs. The properties of the spectrum we found allow the establishment of some structural properties of (α, ω)-graphs.

The spectrum of the Laplacian of Kähler manifolds
We strengthen some results on the spectrum of the Laplacian for 0- and 1-forms [8], [9] on Kähler manifolds and give some new results for the 2-forms.

The Laplacian spectrum of graphs
. The paper is essentially a survey of known results about the spectrum of the Laplacian matrix of graphs with special emphasis on the second smallest Lapla-cian eigenvalue λ2 and its relation to numerous graph invariants, including connectivity ...

For the Weinstein Laplacian considered on the Hilbert space which makes it a self-adjoint operator, the Von Neumann spectral decomposition is given. As applications, a new integral representation for the Weinstein heat kernel is given. Also, it is proved

The spectrum of the periodic p-Laplacian
We consider one-dimensional p-Laplacian eigenvalue problems of the form- ?p u = (? - q) | u |p - 1 sgn u, on (0, b), together with periodic or separated boundary conditions, where p > 1, ?p is the p-Laplacian, q ? C1 [0, b], and b > 0, ? ? R.

Model selection for network data based on spectral information
In this work, we explore the extent to which the spectrum of the graph Laplacian can characterize the probability distribution of random graphs for the purpose of model evaluation and model selection for network data applications.

Evolution of laplacian spectrum under Hamilton's Ricci flow
Spectrum of the Laplacian-Beltrami operator on closed Riemannian manifolds were extensively studied by geometric analysts since 1970s. The results obtained by S.Y. Cheng, Peter Li and S.T.
