Inverse problems of recovering the coefficients of Sturm-Liouville problemswith the eigenvalue parameter linearly contained in one of the boundaryconditions are studied: (1) from the sequences of eigenvalues and normingconstants; (2) from two spectra. Necessary and sufficient conditions for thesolvability of these inverse problems are obtained.
