It is well known that a spherically symmetric wave speed problem in a bounded spherical region may be reduced, by means of Liouville transform, to the Sturm–Liouville problem L ( q ) in a finite interval. In this work, a uniqueness theorem for the potential q of the derived Sturm–Liouville problem L ( q ) is proved when the data are partial knowledge of the given spectra and the potential.
