Query: Least-squares for linear elasticity eigenvalue problem   We study the approximation of the spectrum of least-squares operators arising
from linear elasticity. We consider a two-field (stress/displacement) and a
three-field (stress/displacement/vorticity) formulation; other formulations
might be analyzed with similar techniques. We prove a priori estimates and we
confirm the theoretical results with simple two-dimensional numerical
experiments.
