Discrete symmetries:<br />
Parity and time reversal<br />
The operators of the discrete symmetries related to<br />
space time, and , are quite obvious when act<strong>in</strong>g<br />
on four-vectors:<br />
Note: Although at first it looks similar, the parity<br />
operator is not the metric! (position of the <strong>in</strong>dices).
