In this topic https://physics.stackexchange.com/questions/129417/what-is-pseudo-tensor one answer was the next:
The action of parity on a tensor or pseudotensor depends on the number of indices it has (i.e. its tensor rank):
- Tensors of odd rank (e.g. vectors) reverse sign under parity.
- Tensors of even rank (e.g. scalars, linear transformations, bivectors, metrics) retain their sign under parity.
- Pseudotensors of odd rank (e.g. pseudovectors) retain their sign under parity.
- Pseudotensors of even rank (e.g. pseudoscalars) reverse sign under parity.
But I don't understand one thing. Is that statement only for Euclidean three dimensions? I attempted understand it myself. And it is my thoughts. Pseudotensor is determined as:
ˆPi1…iqj1…jp=(−1)AAi1k1⋯AiqkqBl1j1⋯BlpjpPk1…kql1…lp
where (−1)A=sign(det(Aiqkq))=±1.
Let's consider a pseudovector in Euclidean three dimensions. Then det(Aiqkq) is
(−1000−1000−1)
And (−1)A=−1
Let's consider a pseudovector in Euclidean three dimensions. Then det(Aiqkq) is
(−10000−10000−10000−1)
And (−1)A=1
Let's consider a pseudovector in Minkovski space. Then det(Aiqkq) is
(10000−10000−10000−1)
And (−1)A=−1
am I right?
