Abstract
In this work, we investigate the topological effects of spacetime on the Dirac oscillator in the presence of the Aharonov–Casher effect. We establish the Dirac equation that defines the model. The energy spectrum and wave functions are derived as a function of various physical parameters involved in the problem. The energy spectrum of the oscillator is studied in detail. An important conclusion is that the combined influence of parameters changes the allowed energy states of the oscillator.

Appendix A. (1+2) dimensions Gürses metric
The spacetime metric considered by Gürses in three dimensions [34] (see Eq. (7) , notations are same) is given in the form
where
and \(a_{0}, b_{0}, b_{1}, c_{0}, e_{0}\) are arbitrary constants.
After the constants in (A.2), [35] are chosen as
substituting the found forms of \(\phi ,\psi ,h, q,\) in (A.1), the spacetime metric takes on the following new form
Finally, choosing the constants in (A4) as
(1+2) dimensions Gürses metric (7) presented in this work became
