Skew-self-adjoint Dirac systems with a rectangular matrix potential: Weyl theory, direct and inverse problems
B. Fritzsche, B. Kirstein, I. Ya. Roitberg +1
A non-classical Weyl theory is developed for skew-self-adjoint Dirac systems with rectangular matrix potentials. The notion of the Weyl function is introduced and direct and invers…

Weyl functions of Dirac systems and of their generalizations: integral representation, inverse problem, and discrete interpolation
B. Fritzsche, B. Kirstein, A. L. Sakhnovich
Self-adjoint Dirac systems and subclasses of canonical systems, which generalize Dirac systems are studied. Explicit and global solutions of direct and inverse problems are obtaine…
