The Eigenfrequency Spectra of the Interior Problems

  • Gavin R. Thomson

As we saw in the previous chapter, each of the exterior boundary value problems has at most one regular solution. Unfortunately, this is not true for (Dω+) and (Nω+). We prove that (D0ω+) and (N0ω+) have nonzero solutions by establishing their equivalence to certain integral equations that are known to have such solutions. To do so, we construct the kernels of these integral equations—the so-called Green’s tensors. Throughout the chapter we exploit the close connection between system (4.1) and the corresponding homogeneous system governing the equilibrium bending of plates.
