A note on resonant frequencies for a system of elastic wave equations
We present a rather simple proof of the existence of resonant frequencies for the direct scattering problem associated to a system of elastic wave equations with Dirichlet boundary condition. Our approach follows techniques similar to those in Cortés‐Vega (2003).

Periodic solutions of nonlinear vibrating beams
The aim of this paper is to prove new existence and multiplicity results for periodic semilinear beam equation with a nonlinear time‐independent perturbation in case the period is not prescribed. Since the spectrum of the linear part varies with the period, the solvability of the equation depends crucially on the period which can be chosen as a free ...

We show in this paper that the sequence {max|uk|}, where the uk are the eigenfunctions of the problem Δu + λu = 0 in D ⊂ Rn and u = 0 on ∂D, is not bounded generally if one imposes the norm ∫Du2p(x)dx = 1, p = (1), 2, 3, …. The same holds with the norm ∫D|gradu|2pdx = 1 when n > 4p − 1. On the other hand, if D ⊂ R2, resp.
