AnEigenspaceof vectorxconsists of a set of all eigenvectors with the equivalent eigenvalue collectively with the zero vector. Though, the zero vector is not an eigenvector. Let us say A is an “n × n” matrix and λ is an eigenvalue of matrix A, thenx, a non-zero vector, is called...
Then we will compute the Hessians of the complete graph and the complete bipartite graph in Sect. 3. In Sect. 4, we will discuss the strong Lefschetz property of the algebra AM corresponding to a graphic matroid. 2 The eigenvectors and eigenvalues of block matrices In this section, we give...

Versions Notes Abstract In this paper, a Toeplitz construction method based on eigenvalues and eigenvectors is proposed to combine with traditional denoising algorithms, including fractional low-order moment (FLOM), phased fractional low-order moment (PFLOM), and correntropy-based correlation (CRCO) me...
Specifically, in this study, based on a dataset covering nine years of stock prices, we systematically investigate the stock markets of China and the US using random matrix theory (RMT) to study and compare the correlation properties and the dynamics of eigenvalues and eigenvectors. The findings ...
It turned out that the evolution of the eigenvalues is governed by a system of deterministic first-order differential equations subject to random initial conditions, with the initial positions and velocities expressed in terms of the eigenvalues and eigenvectors of H. In addition, under suitable ...
One weakness of his conceptualization occurs with multiple zero eigenvalues: their eigenspace is not unique [33,34], and hence is an arbitrary choice among all of the possible correct eigenvectors for a repeated (non-degenerate) eigenvalue from a real symmetric matrix. Consequently, if only a ...
, x q − v will also be eigenvectors of λ in G − v , and clearly these q − 1 eigenvectors are linearly independent. If x 1 also has its vth entry equal to zero, then x 1 − v will also be an eigenvector of λ in G − v that is linearly independent of x 2 −...
