non-self-adjoint operatordamped wave equationThe spectrum of the damped wave operator for a bounded do-main in R~2 is shown to be related to the asymptotic average of the damping function by the geodesic flow. This allows the calculation of an asymptotic expression for the distribution of the...
of the point spectra. They then went on to prove that whenZ\le 137(or ratherZ < \frac{1}{\alpha _{{\textrm{S}}}), then the eigenvalues of the unique self-adjoint operator with anomalous magnetic moment converge to those of the distinguished self-adjoint extension of the one without....
