On Eigenvalues of the Generator of a C0-Semigroup Appearing in Queueing Theory

We describe the point spectrum of the generator of a C0-semigroup associated with the M/M/1 queueing model that is governed by an infinite system of partial differential equations with integral boundary conditions. Our results imply that the essential growth bound of the C0-semigroup is 0 and, there...
