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

Diomba Sambou

We study the spectral shift function (SSF) $\xi (\lambda )$ and the resonances of the operator $H_V:=(\sigma \cdot (-i\nabla -\text{A}){)}^2+V$ in $L^2({\mathbb{R}}^3)$ near the ori…
