Complex Eigenvalues of the Deformation Gradient

Mathematics and Mechanics of Solids, 2001
Thomson and Tait pointed out that the deformation gradient F at a point X in a continuous medium has at least one real positive eigenvalue and showed that material line elements along N, the corresponding right eigenvector of F, retain their direction in the deformation.

$U$-Eigenvalues’ Inclusion Sets of Complex Tensors

Annals of Applied Mathematics, 2023
In this paper, we study some inclusion sets of $US$-eigenvalues and $U$-eigenvalues based on quantum information. We give three inclusion sets theorems of $US$-eigenvalues and two inclusion sets theorems of $U$-eigenvalues. And we obtain the relationships among these inclusion sets. Some numerical examples are shown to illustrate the conclusions.

Large-scale complex eigenvalue problems

Journal of Computational Physics, 1989
The author gives a review about methods for solving eigenvalue problems. At first some results of linear algebra, necessary for solving linear systems of equations and eigenvalue problems, are presented. General methods (QR-, QZ-algorithm) for solving eigenvalue problems are briefly discussed, whereas methods suitable for large-scale problems by ...

Complex Eigenvalues of Corrugated Waveguide

13th European Microwave Conference, 1983, 2006
A new method for resolving the boundary condition eigenvalue equation of the cylindrical corrugated system is given. According to this method, the real or the "imaginary roots of the eigenvalue equation can be computed rapidly and easily, especially, the superiority is manifested for computing the complex roots.

Regge poles as complex eigenvalues

Journal of Physics A: Mathematical and General, 1998
Summary: The authors report a new direct method for calculating Regge pole positions and residues. Upon introduction of an absorbing optical potential sufficiently far in the asymptotic region, the problem reduces to several iterative diagonalizations of a symmetric complex matrix. The method is tested on well-studied cases of potential scattering.

Eigenvalues of complex Hamiltonians with -symmetry. I

Physics Letters A, 1998
Abstract Making use of our earlier work [Ann. of Phys. 261 (1997) 180] we investigate the reality of eigenvalues of the complex PT -symmetric quartic oscillator. In contradistiction to the Zinn-Justin-Bessis case we have studied elsewhere [Phys. Lett.
