Abstract
The spectral problem in a bounded domain Ω⊂Rn is considered for the equation Δu= λu in Ω, −u=λ∂υ/∂ν on the boundary of Ω (ν the interior normal to the boundary, Δ, the Laplace operator). It is proved that for the operator generated by this problem, the spectrum is discrete and consists of two series of eigenvalues {λ 0 j } ∞ j=1 and {λ ∞ j } ∞ j=1 , converging respectively to 0 and +∞. It is also established that
The constants are explicitly calculated.
