Linear Algebra and its Applications, 1982 AbstractWe study the dependence of the eigenvalues of a tridiagonal matrix upon off-diagonal entries. The change in the eigenvalues when a cross-diagonal product approaches zero or infinity is estimated.

Shape Perturbation of Grushin Eigenvalues [PDF]
The Journal of Geometric Analysis, 2021 AbstractWe consider the spectral problem for the Grushin Laplacian subject to homogeneous Dirichlet boundary conditions on a bounded open subset of $${\mathbb {R}}^N$$ R N .

Challenging eigenvalue perturbation problems
Linear Algebra and its Applications, 1998 AbstractFor estimating error bound of computed eigenvalues of a matrix, we need more practical perturbation theory of eigenvalues of matrices. In this paper two problems are put forward in such direction.

Expansion of eigenvalues of the perturbed discrete bilaplacian [PDF]
Monatshefte für Mathematik, 2022 AbstractWe consider the family $$\begin{aligned} {\widehat{{ H}}}_\mu := {\widehat{\varDelta }} {\widehat{\varDelta }} - \mu {\widehat{{ V}}},\qquad \mu \in {\mathbb {R}}, \end{aligned}$$

Real Valued Functions for the BFKL Eigenvalue
Universe, 2021 We consider known expressions for the eigenvalue of the Balitsky-Fadin-Kuraev-Lipatov (BFKL) equation in N=4 super Yang-Mills theory as a real valued function of two variables.

Soft photon radiation and entanglement
European Physical Journal C: Particles and Fields, 2021 We study the entanglement between soft and hard particles produced in generic scattering processes in QED. The reduced density matrix for the hard particles, obtained via tracing over the entire spectrum of soft photons, is shown to have a large ...
