Microscopic correlations of non-Hermitian Dirac operators in three-dimensional QCD [PDF]
, 2001 In the presence of a non-vanishing chemical potential the eigenvalues of the Dirac operator become complex. We calculate spectral correlation functions of complex eigenvalues using a random matrix model approach.

A COMPUTATION PERSPECTIVE FOR THE EIGENVALUES OF CIRCULANT MATRICES INVOLVING GEOMETRIC PROGRESSION
Jurnal Matematika UNAND, 2023 In this article, the eigenvalues and inverse of circulant matrices with entries in the first row having the form of a geometric sequence are formulated explicitly in a simple form in one theorem. The method for deriving the formulation of the determinant

Design of Multi-Loop Modal Control Systems for Plants Having Complex Eigenvalues
Measurement + Control, 1968 In this paper a design procedure is developed which makes it possible to alter both the real and imaginary parts of any number of pairs of conjugate complex plant eigenvalues: this procedure alters one pair of conjugate eigenvalues at a time by the ...

Unquenched complex Dirac spectra at nonzero chemical potential: Two-colour QCD lattice data versus matrix model [PDF]
, 2006 We compare analytic predictions of non-Hermitian chiral random matrix theory with the complex Dirac operator eigenvalue spectrum of two-color lattice gauge theory with dynamical fermions at nonzero chemical potential.

Eigenvalue localization for complex matrices
The Electronic Journal of Linear Algebra, 2014 Let $A$ be an $n\times n$ complex matrix with $n\geq 3$. It is shown that at least $n-2$ of the eigenvalues of $A$ lie in the disk \begin{equation*}\left\vert z-\frac{\func{tr}A}{n}\right\vert \leq \sqrt{\frac{n-1}{n}\left(\sqrt{\left( \left\Vert A\right\Vert _{2}^{2}-\frac{\left\vert \func{tr} A\right\vert ^{2}}{n}\right) ^{2}-\frac{\left\Vert A ...

On the eigenvalues of some nonhermitian oscillators [PDF]
, 2013 We consider a class of one-dimensional nonhermitian oscillators and discuss the relationship between the real eigenvalues of PT-symmetric oscillators and the resonances obtained by different authors.

Transformation of Eigenvalues of the Zakharov–Shabat Problem under the Effect of Soliton Collision [PDF]
Известия Саратовского университета. Новая серия: Физика, 2020 Background and Objectives: The Zakharov–Shabat spectral problem allows to find soliton solutions of the nonlinear Schrodinger equation. Solving the Zakharov–Shabat problem gives both a discrete set of eigenvalues λj and a continuous one.
