Inverse spectral problems for Bessel operators

We study the inverse spectral problem for a class of Bessel operators given in L2(0,1) by the differential expression with and a real-valued function v Lp(0,1), p [1,∞), subject to various boundary conditions. We describe completely the spectral data of these operators, i.e., the spectra and corresponding norming constants, and give the algorithm of reconstruction of v from the spectral data.
