Body resonances for classical waves

Andrea Mantile, Andrea Posilicano

We provide a detailed study of the spectral properties of the linear operator $H(\epsilon )=-({\epsilon }^2\ddot{I}{‡}_{\hat{I}{\text{c◯}}_{\epsilon }}+\ddot{I}{‡}_{\hat{I}{\text{c◯}}_{\epsilon }^c})\hat{I}”$ modeling, through…
