Abstract

For the Schroedinger equation \(−d^2u/dx^2 + q(x)u = λu\) on a finite \(x\)-interval, there is defined an “asymmetry function” \(a(λ; q)\), which is entire of order 1/2 and type 1 in \(λ\). Our main result identifies the classes of square-integrable potentials \(q(x)\) that possess a common asymmetry function \(a(λ)\). For any given \(a(λ)\), there is one potential for each Dirichlet spectral sequence.
