Hey folks,
I am trying to piece together what the point of the Ricci Decomposition is.
Wikipedia explains what it is but not really why.
I understand that we can break down the Ricci Tensor into:
1) Scalar part
2) Semi-traceless
3) Traceless (Weyl Tensor)
I have the following questions:
a) WHY break it down.
b) Do the first 2 have a special name in that the 3rd is called the Weyl Tensor.
c) What does semi traceless mean?
As always, thanks in advance.
