Abstract

In this work, we consider the inverse spectral problem for the impulsive Sturm–Liouville problem on (0,π) with the Robin boundary conditions and the jump conditions at the point π2. We prove that the potential M(x) on the whole interval and the parameters in the boundary conditions and jump conditions can be determined from a set of eigenvalues for two cases: (i) the potential M(x) is given on (0,(1+α)π4); (ii) the potential M(x) is given on ((1+α)π4,π), where 0<α<1, respectively. It is also shown that the potential and all the parameters can be uniquely recovered by one spectrum and some information on the eigenfunctions at some interior point.
