Abstract
We study the (2+1)-dimensional κ-Dirac scalar-Coulomb problem in the framework of κ-Poincaré-Dirac equation.It is found that for a scalar-Coulomb coupling, the nonrelativisticlimit yields a nonvanishing energy correction to the first order in the quantum group parameter (ε = κ 1),while the energy remains unaltered (to the first order in ε) in the case of the vector-Coulomb coupling in (2+1)dimensions.
