Spectral theory for domains in R(n) of finite measure
Let Ω be a measurable subset of R(n) of finite positive Lebesgue measures. The following two problems are considered: (i) Find commuting self-adjoint extensions of the minimal operators -i(∂)/∂x(k), k = 1,..., n (Ω open). (ii) Find a set Λ ⊂ R(n) such that the functions e(λ) = exp(iλ(1)x(1) +... + i...
