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…
