A special class of triple starlike trees characterized by Laplacian spectrum
Two graphs are said to be cospectral with respect to the Laplacian matrix if they have the same Laplacian spectrum. A graph is said to be determined by the Laplacian spectrum if there is no other non-isomorphic graph with the same Laplacian spectrum.

On Laplacian Equienergetic Signed Graphs
The Laplacian energy of a signed graph is defined as the sum of the distance of its Laplacian eigenvalues from its average degree. Two signed graphs of the same order are said to be Laplacian equienergetic if their Laplacian energies are equal.

Spektrum Laplace pada graf kincir angin berarah (Q_k^3)
Suppose that 0 = µ0 ≤ µ1 ≤ ... ≤ µn-1 are eigen values of a Laplacian matrix graph with n vertices and m(µ0), m(µ1), …, m(µn-1) are the multiplicity of each µ, so the Laplacian spectrum of a graph can be expressed as a matrix 2 × n whose line elements ...

Gluon Propagator on Coarse Lattices in Laplacian Gauges [PDF]
The Laplacian gauge is a nonperturbative gauge fixing that reduces to Landau gauge in the asymptotic limit. Like Landau gauge, it respects Lorentz invariance, but it is free of Gribov copies; the gauge fixing is unambiguous.

Isospectral infinite graphs and networks and infinite eigenvalue multiplicities
We considerthe continuous Laplacian on infinite locally finite networks undernatural transition conditions as continuity at the ramificationnodes and Kirchhoff flow conditions at all vertices.

Let G be a graph with n vertices, and let LG and QG denote the Laplacian matrix and signless Laplacian matrix, respectively. The Laplacian (respectively, signless Laplacian) permanental polynomial of G is defined as the permanent of the characteristic ...

Laplacian Pattern Formation [PDF]
The formation of snowflakes, viscous fingers and electrodeposits is governed by analogous equations : these structures are all Laplacian patterns. In this paper we review model experiments and computer simulations which are widely used to study diverse morphologies resulting from the motion of unstable interfaces.

Unravelling how the human brain structure gives rise to function is a central question in neuroscience and remains partially answered. Recent studies show that the graph Laplacian of the human brain’s structural connectivity (SC) plays a dominant role in

Fractional Laplacian pyramids [PDF]
We provide an extension of the L 2 -spline pyramid (Unser et al., 1993) using polyharmonic splines. We analytically prove that the corresponding error pyramid behaves exactly as a multi-scale Laplace operator. We use the multiresolution properties of polyharmonic splines to derive an efficient, non-separable filterbank implementation.
