A finite set of equilibria for the indeterminacy of linear rational expectations models [PDF]
, 2014 This paper demonstrates the existence of a finite set of equilibria in the case of the indeterminacy of linear rational expectations models. The number of equilibria corresponds to the number of ways to select n eigenvectors among a larger set of ...

On Universal Eigenvalues and Eigenvectors of Hypermatrices [PDF]
arXiv, 2023 A cubic hypermatrix of order $d$ can be considered as a structure matrix of a tensor with covariant order $r$ and contra-variant order $s=d-r$. Corresponding to this matrix expression of the hypermatrix, an eigenvector $x$ with respect to an eigenvalue $\lambda$ is proposed, called the universal eigenvector and eigenvalue of the hypermatrix.

Partial eigenvalue assignment problem of linear control systems using orthogonality relations [PDF]
Acta Montanistica Slovaca, 2006 The partial eigenvalue assignment is the problem of reassigning a part of the open-loop spectrum of a linear system by a feedback control, leaving the rest of the spectrum invariant.

A New Fixed Point Result of Perov Type and Its Application to a Semilinear Operator System
Mathematics, 2019 In this paper, we present a new generalization of the Perov fixed point theorem on vector-valued metric space. Moreover, to show the significance of our result, we present both a nontrivial comparative example and an application to a kind of semilinear ...

Localization and universality of eigenvectors in directed random graphs [PDF]
Phys. Rev. Lett. 126, 040604 (2021), 2020 Although the spectral properties of random graphs have been a long-standing focus of network theory, the properties of right eigenvectors of directed graphs have so far eluded an exact analytic treatment. We present a general theory for the statistics of the right eigenvector components in directed random graphs with a prescribed degree distribution ...
