The position operator in coordinate representation is:
Xab=aδ(a-b)
this is diagonal as expected
The momentum operator turns out to look like
Pab=-ih∂aδ(a-b)
Now, this is not supposed to be diagonal because it does not commute with X.
However it looks pretty diagonal to me.
What am I missing?
Xab=aδ(a-b)
