Nonlinear Dirac equations and nonlinear gauge transformations
H. -D. Doebner, R. Zhdanov
Nonlinear Dirac equations (NLDE) are derived through a group N^2 of nonlinear (gauge) transformation acting in the corresponding state space. The construction generalises a constru…

Infinite Quasi-Exactly Solvable Models
H. D. Doebner, K. Lazarow, A. G. Ushveridze
We introduce a new concept of infinite quasi-exactly solvable models which are constructable through multi-parameter deformations of known exactly solvable ones. The spectral probl…
