  • The authors give a constructive algorithm for the inverse Sturm-Liouville operator in non-potential form. They emphasize the unknown impedance case, i.e. the recovery of the coefficient a(x) in (a(x)u'(x))'+ lambda a(x)u(x)=0 from spectral data. It is shown that many of the formulations of this problem are equivalent to solving an overdetermined boundary value problem for a certain hyperbolic operator. An iterative procedure for solving this latter problem is developed and numerical examples… CONTINUE READING
