On the spectral properties of non-selfadjoint discrete Schrödinger operators

Olivier Bourget, Diomba Sambou, Amal Taarabt

Let $H_{0}$ be a purely absolutely continuous selfadjoint operator acting on some separable infinite-dimensional Hilbert space and $V$ be a compact non-selfadjoint perturbation. We r…

Spectral shift function and Resonances near the low ground state for Pauli and Schrödinger operators

Diomba Sambou

We study the spectral shift function (SSF) $ξ (λ)$ and the resonances of the operator $H_{V} := (σ \cdot (- i \nabla - A))^{2} + V$ in $L^{2} (R^{3})$ near the ori…
