Essential spectra and eigenvalue asymptotics of Fourier blocks of the elastic Neumann-Poincar\'e operator on tori

We study the spectral behavior of the Fourier blocks of the elastic Neumann-Poincar\'e operator on a torus. For the full elastic Neumann-Poincar\'e operator, it is known that eigenvalues accumulate at three points, namely zero and a symmetric pair of nonzero points determined by the Lam\'e parameters. It remains unclea...
