Consider the equation \[ -y''+V(x)y=k^2y,\; -\infty<x<\infty, \tag{1} \] where \(V(x)\) is real and \((1+| x| )| V(x)| \in L(-\infty,\infty)\). Let \(e(x,k)\) and \(g(x,k)\) are the Jost solutions for (1) such that \[ e(x,k)=\exp(ikx)(1+o(1))\text{ as }x\to +\infty,\quad g(x,k)=\exp(-ikx)(1+o(1))\text{ as } x\to -\infty. \] Then \(e(x,k)=a(k)g(x,-k)+b(k)g(x,k)\). The inverse problem of recovering the potential \(V(x)\) from the given \(b(k)\) is studied, and the nonuniqueness for this incomplete inverse problem is analysed.For the entire collection see [Zbl 1052.35004].
