Discrete Symmetries and Generalized Fields of Dyons

We have studied the different symmetric properties of the generalized Maxwell’s–Dirac equation along with their quantum properties. Applying the parity (℘), time reversal ( Tmathcal{T} ), charge conjugation (Cmathcal{C}) and their combined effect like parity time reversal (PTmathcal{PT}), charge conjugation and parity (CPmathcal{CP}) and CPTmathcal{CP}T transformations to various equations of generalized fields of dyons, it is shown that the corresponding dynamical quantities and equations of dyons are invariant under these discrete symmetries.
