Hi, thanks for the reply and advice.
Sorry I didn't supply a reference, I didn't realize
that this decomposition was not more common.
It is very common in Gravitational Wave analysis.
This link gives a definition of the spin weighted spherical harmonics

Hi All,
Can someone tell me why gravitational waves are always decomposed in spin weighted spherical harmonics with spin weight -2 ?
I'm assuming you can hand wave the answer with something to do with the 'graviton' being a spin 2 particle but this isn't very satisfying to me.
Are there any...
Hey SC,
You should always be mindful of which reference frame you are viewing a given physical situation.
By virtue of the equivalence principle the physical laws are independent
of the reference frame but what different observers 'sees' can be different depending on the
reference frame.
For...
Hey Guys, thanks a lot for replying
Thanks for the tip with arranging the indices using latex.
After some thought I think I have figured out what I was asking
Cheers guys
Hello all,
I've been going through Bernard Schutz's A First Course In General Relativity, On Chapter 5 questions atm.
Should the Christoffel Symbols for a coordinate system (say polar) be the same for vectors and one-forms in that coordinate system?
I would have thought yes, but If you...
