Eigenvalue asymptotics, inverse problems and a trace formula for the linear damped wave equation

Denis Borisov, Pedro Freitas

We determine the general form of the asymptotics for Dirichlet eigenvalues of the one-dimensional linear damped wave operator. As a consequence, we obtain that given a spectrum cor…
