AN INVERSE EIGENVALUE PROBLEM FOR ONE DIMENSIONAL DIRAC OPERATORS

摘要

We consider an inverse eigenvalue problem for Dirac operators on finite intervals. We show that if for a mu is an element of C the system {exp 2i lambda(n) x, exp 2i mu x} is closed in L-p [- pi, pi], then there is at most one L-p -potential with the eigenvalues lambda(n). The result corresponds to the case of Schrodinger operators.
