Abstract
The structured operators and corresponding operator identities, which appear in inverse problems for self-adjoint and skew-self-adjoint Dirac systems with rectangular potentials, are studied in detail. In particular, it is shown that integral operators with kernels close to displacement kernels are included in this class. A special case of positive and factorizable operators is dealt with separately.
