Abstract: | In this paper, we discuss the inverse problem for indefinite Sturm-Liouville operators on the finite interval [a, b]. For a fixed index n(n = 0, 1, 2, ??), given the weight function ??(x), we will show that the spectral sets {?? n (q, h a , h k )} k=1 +?? and {?? ?n (q, h b , h k )} k=1 +?? for distinct h k are sufficient to determine the potential q(x) on the finite interval [a, b] and coefficients h a and h b of the boundary conditions. |
