Abstract
In this paper, the reconstruction of a differential operator from incomplete spectral characteristics is concerned. We prove that coefficients of a second-order differential equation with the eigen-parameter appearing at the right-end boundary condition can be uniquely determined from incomplete nodal data. The new results in this paper are unlike to the known results for the classical Sturm-Liouville operator in [21].
