The Spectral Shift Function for Non-Self-Adjoint Perturbations

Vincent Bruneau, Nicolas Frantz, François Nicoleau

This paper is devoted to the definition and analysis of the spectral shift function (SSF) associated with non-self-adjoint perturbations of self-adjoint operators. Motivated by app…

A Poincaré-Steklov map for the MIT bag model

Badreddine Benhellal, Vincent Bruneau, Mahdi Zreik

The purpose of this paper is to introduce and study Poincaré-Steklov (PS) operators associated to the Dirac operator with the so-called MIT bag boundary condition. In a domai…

Threshold singularities of the spectral shift function for geometric perturbations of magnetic Hamiltonians

Vincent Bruneau, Georgi Raikov

We consider the 3D Schrödinger operator with constant magnetic field of scalar intensity , and its perturbations (resp., ) obtained by imposing Dirichlet…

Eigenvalue and Resonance Asymptotics in perturbed periodically twisted tubes: Twisting versus Bending

Vincent Bruneau, Pablo Miranda, Daniel Parra +1

We consider the Dirichlet Laplacian in a three-dimensional waveguide that is a small deformation of a periodically twisted tube. The deformation is given by a bending and an additi…

Resonances near Thresholds in slightly Twisted Waveguides

Vincent Bruneau, Pablo Miranda, Nicolas Popoff

We consider the Dirichlet Laplacian in a straight three dimensional waveguide with non-rotationally invariant cross section, perturbed by a twisting of small amplitude. It is well…

Spectral Properties of Harmonic Toeplitz Operators and Applications to the Perturbed Krein Laplacian

Vincent Bruneau, Georgi Raikov

We consider harmonic Toeplitz operators where is the orthogonal projection onto ${\mathcal H}(Ω) = \l…
