Tensors and Relativity: Hints 6
- (2) This is straight out of section 6.5.1 of the lecture notes.
- (3) First write down the standard transformation laws which take
you from (x,y,z) to
. Next calculate the basis vectors
and then the metric from
. The metric for a 2- sphere, then follows by taking
r=1, so dr=0.
- (4) Here it is enough to show that the Christoffel symbols all vanish.
- (5) The only non- zero component is
, so
that's all you need to calculate.
- (6) In both parts use a local inertial frame to prove the results.
- (7) Calculate
, where
is an affine
parameter along the geodesic.
