对一般非对称算子A,证明了其特征值的负真实的部分的阶矩γ≥1与其对称部分H=12[A+A]的负特征值的阶矩γ有界.作为应用,我们得到了非自伴Schrodinger算子的Lieb-Thirring估计。特别是,我们恢复了Frank等人最近的结果。77,309(2006)]。我们还讨论了薛定谔自伴算子的共振矩。
For general nonsymmetric operators A, we prove that the moment of order γ≥1 of negative real parts of its eigenvalues is bounded by the moment of order γ of negative eigenvalues of its symmetric part H=12[A+A∗]. As an application, we obtain Lieb–Thirring estimates for non-self-adjoint Schrodinger operators. In particular, we recover recent results by Frank et al. [Lett. Math. Phys. 77, 309 (2006)]. We also discuss moment of resonances of Schrodinger self-adjoint operators.
