I wonder if I can chose any 4x4 matrices [tex]\gamma^\mu[/tex] which fullfil anticommutationn relations(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\{\gamma^\mu,\gamma^\nu \}=2g^{\mu\nu} [/tex] as a matricies

in Dirac equation:

[tex]

i \gamma^\mu \partial_\mu \psi= m \psi

[/tex].

What changes in the theory if I chose different matricies?

(of course I have to consistently use this different matricies)

What if this matricies has explicit time dependence and I'm

looking for solutions evolving in time as [tex] \exp (-i\omega t) [/tex].
