Let A(G) be the adjacency matrix of a graph G with λ1(G), λ2(G), . . . , λn(G) its eigenvalues in non-increasing order. Call the number Sk(G) := ∑ n i=1 λ i (G) (k = 0, 1, . . . , n − 1) the kth spectral moment of G. Let S(G) = (S0(G), S1(G), . . . , Sn−1(G)) be the sequence of spectral moments of G. For two graphsG1 and G2, we have G1 ≺s G2 if Si(G1) = Si(G2) for i = 0, 1, . . . , k−1 and Sk(G...

In this paper, the method of identifying of the similar solar flux tubes from image sequence EUVI/STEREO is presented. Using the oriented coronal curved loop tracing, the loops of an image are labeled. Based on local maxima intensities, the width of loops is determined. The Zernike moments of each loop are calculated and fed to probabilistic network classifier. Also, 588 loops from STEREO are s...
We compute an asymptotic expansion with precision 1/n of the moments of the expected empirical spectral measure of Wigner matrices of size n with independent centered entries. We interpret this expansion as the moments of the addition of the semicircle law and 1/n times an explicit signed measured with null total mass. This signed measure depends only on the second and fourth moments of the ent...
