A local directional growth estimate of the resolvent norm

Horia D. Cornean, Henrik Garde, Arne Jensen +1

We study the resolvent norm of a certain class of closed linear operators on a Hilbert space, including unbounded operators with compact resolvent. It is shown that for any point i…

Instability of resonances under Stark perturbations

Arne Jensen, Kenji Yajima

Let $H^{ε} = - \frac{d ^{2}}{d x ^{2}} + ε x + V$ , $ε \geq 0$ , on $L^{2} (R)$ . Let $V = \sum_{k = 1}^{N} c_{k} ∣ ψ_{k} ⟩ ⟨ ψ_{k} ∣$ be a rank $N$ operator, where the…
