Asymptotic Distribution of Eigenfrequencies for Damped Wave Equations
Asymptotic Distribution of Eigenfrequencies for Damped Wave Equations
The eigenfrequencies associated to a damped wave equation, are known to belong to a band parallel to the real axis. We establish Weyl asymptotics for the distribution of the real parts of the eigenfrequencies, we show that up to a set of density 0, the eigenfrequencies are confined to a …
