Inverse spectral problems for Dirac operators on a finite interval

Abstract

We consider the direct and inverse spectral problems for Dirac operators that are generated by the differential expressions \mathfrak t_q:=\frac{1}{i}[I&0 0&-I]\frac{d}{dx}+[0&q q^*&0] and some separated boundary conditions. Here qq is an r×rr\times r matrix-valued function with entries belonging to L2((0,1),C)L_2((0,1),\mathbb C) and II is the identity r×rr\times r matrix. We give a complete description of the spectral data (eigenvalues and suitably introduced norming matrices) for the operators under consideration and suggest an algorithm of reconstructing the potential qq from the corresponding spectral data.
