# I Vectors in Minkowski space and parity

#### illuminates

It is known that vectors change them sing under the influence of parity when $(x,z,y)$ change into $(-x,-z,-y)$
$$P: y_{i} \rightarrow -y_{i}$$
where $i=1,2,3$
But what about vectors in Minkowski space? Is it true that
$$P: y_{\mu} \rightarrow -y_{\mu}$$
where $\mu=0,1,2,3$.
If yes how one can check it?

The action of parity reversal is the same for the space components. Time reversal changes the sign of the T bits.

Just to be clear, no.
