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…
Recovery of Dirac system from the rectangular Weyl matrix function
B. Fritzsche, B. Kirstein, I. Ya. Roitberg +1
Weyl theory for Dirac systems with rectangular matrix potentials is non-classical. The corresponding Weyl functions are rectangular matrix functions. Furthermore, they are non-expa…
Weyl theory and explicit solutions of direct and inverse problems for a Dirac system with rectangular matrix potential
B. Fritzsche, B. Kirstein, I. Ya. Roitberg +1
A non-classical Weyl theory is developed for Dirac systems with rectangular matrix potentials. The notion of the Weyl function is introduced and the corresponding direct problem is…
