The low-frequency spectrum of small Helmholtz resonators

We analyse the spectrum of the Laplace operator in a complex geometry, representing a small Helmholtz resonator. The domain is obtained from a bounded set Ω⊂Rn by removing a small obstacle Σ ⊂Ω of size >0. The set Σ essentially separates an interior domain Ωεinn (the resonator volume) from an ext...
