Abstract

We discuss the eigenvalues E_j of Schrödinger operators −Δ+V in L^2(R^d) with complex potentials V ∈ L^p, p < ∞. We show that (A) Re E_j → ∞ implies Im E_j → 0, and (B) Re E_j → E ∈ [0,∞) implies (Im E_j) ∈ ℓ^q for some q depending on p. We prove quantitative versions of (A) and (B) in terms of the L^p-norm of V.
