The normalized distance Laplacian, ( G ) = I T ( G ) 1/2 ( G ) T ( G ) 1/2 , is introduced. This is analogous to the normalized Laplacian matrix, ( G ) = I D ( G ) 1/2 A ( G ) D ( G ) 1/2 , where D ( G ) is the diagonal matrix of degrees of the ...
Many interesting graphs have rich structure which can help in determining the eigenvalues associated with a particular graph matrix. This survey looks at some common techniques in working with and determining the eigenvalues associated with the normalized Laplacian matrix, in addition to some algebraic ...

The Laplacian, or the normalized Laplacian matrix, of G is de?ned as L = I ? A 1 ? where I is the identity matrix, A = (? aij ) is the normalized adjacency matrix, a ?ij = √ , di dj if vertices i and j are connected, and a ?ij = 0 otherwise. This approach involves ...

We consider the normalized Laplacian matrix for signed graphs and derive interlacing results for its spectrum. In particular, we investigate the effects of several basic graph operations, such as edge removal and addition and vertex contraction, on the Laplacian eigenvalues. We also study vertex ...
As such, do g = inputImage(:);, assuming that we have converted to double and normalized between 0 and 1. When you finally solve for u, you can reshape it back to an image by doing: u = reshape(u, size(inputImage, 1), size(inputImage, 2)); u may also be...

In [9–11,18,19], different spectral properties of Laplacian and signless Laplacian of a uniform hypergraph, defined by using tensor, have been studied. In 2015, Hu and Qi introduced the normalized Laplacian of a uniform hypergraph and analyzed its spectral properties [8]. Show abstract ...
