Abstract:

This paper studies inverse spectral problems for the Sturm-Liouville operator on $(0,1)$ with the Robin boundary conditions and a discontinuity at $x=d\in(0,\frac{1}{2}]$. Suppose that the known data contains one subspectrum, the potential function on $(d,1)$ as well as partial parameters in the right boundary condition and the discontinuous conditions. The paper proves the local solvability and stability for the inverse problems of recovering the potential function on $(0,d)$ and the parameter in left boundary condition, where the known potential and the parameter in the right boundary condition are allowed to contain errors.

Key words: Sturm-Liouville operator, Discontinuity condition, Local solvability, Stability
