Abstract
This paper investigates singular discrete Dirac equations and establishes famous Weyls classification for these equations. First, the limit-circle and limit-point classifications are obtained. Then, the existence of boundary conditions is demonstrated. Finally, it is shown that the limit-circle case does not occur for these equations.
