In this work, we study the (2+1)-dimensional Dirac oscillator in the
presence of a homogeneous magnetic field in an Aharonov-Bohm-Coulomb
system. To solve our system, we apply the left-handed and right-handed
projection operators in the Dirac oscillator to obtain a biconfluent
Heun equation. Next, we explicitly determine the energy spectrum for the
bound states of the system and their exact dependence on the cyclotron
frequency omega(c) and on the parameters Z and Phi(AB) that characterize
the Aharonov-Bohm-Coulomb system. As a result, we observe that by
adjusting the frequency of the Dirac oscillator to resonate with the
cyclotron half-frequency the energy spectrum reduces to the rest energy
of the particle. Also, we determine the exact eigenfunctions, angular
frequencies, and energy levels of the Dirac oscillator for the ground state (n = 1) and the first excited state (n = 2). In this case, the
energy levels do not depend on the homogeneous magnetic field, and the
angular frequencies are real and positive quantities, increase
quadratically with the energy and linearly with omega(c). (C) 2018
