Covariances and invariances of the Beltrami-Maxwell postulates

The newly formulated Beltrami-Maxwell postulates (BMP) for complex-valued time-dependent fields and sources have a richer structure than the commonly used Maxwell postulates (MP) for the real-valued time-dependent fields and sources of conventional electromagnetism. In the paper the Lorentz covariance of the BMP is proved and the transformation rules between inertial frames are provided. Furthermore, their scale invariance are explored, both in isotropic and anisotropic settings, and their conjugate invariance delineated in the context of electromagnetism
