摘要：
The difficulties associated with the application of the 1/N-expansion to the Dirac equation have been resolved by applying the method of HBAR-expansion. This technique does not involve converting the initial equation into a Schrodinger-like or Klein-Gordon-like form. Obtained recurrence formulae have a simple form both for the ground and excited states, and allow one to find the 1/N-corrections of an arbitrary order in any of the 1/N-expansion schemes. The method restores the exact results for the Coulomb potential.
