abstract = {The paper deals with a Dirichlet spectral problem for an elliptic operator with
ε-periodic coefficients in a 3D bounded domain of small thickness
δ. We study the asymptotic behavior of the spectrum as
ε and δ tend to zero. This asymptotic behavior depends
crucially on whether ε and δ are of the same order
(δ ≈ ε), or ε is much less than
δ(δ = ετ, τ < 1),
or ε is much greater than
δ(δ = ετ, τ > 1).
We consider all three cases. },
