Relativistic Wave Equations

  title={Relativistic Wave Equations},
  author={R. D’auria and Mario Trigiante},
In the previous chapter we have recalled the basic notions of non-relativistic quantum mechanics. We have seen that, in the Schroedinger representation, the physical state of a free particle of mass m is described by a wave function \(\psi (\mathbf{x},t)\) which is itself a classical field having a probabilistic interpretation.
