Uniqueness for Inverse Sturm-Liouville Problems with a Finite Number of   Transmission Conditions
  We establish various uniqueness results for inverse spectral problems of Sturm-Liouville operators with a finite number of discontinuities at interior points at which we impose the usual transmission conditions. We consider both the case of classical Robin and of eigenparameter dependent boundary conditions.
