- Hello sci.math
-
- Is it always possible to make a change of coordinates that gives a
- geodisic coordinate system at any point for a general metric that can
- contain an anti-symmetric part? If so, could you supply it? eg.
-
- i i i m m n n
- x' = x - x + {mn,i}(x - x )(x - x ) where (0) denotes the value at pole
- (0) (0) (0) (0)
-
- is such a transformation for a symmetric metric.
-
- Also, can anyone verify or contest the validity of a result for the
- curvature tensor for a general metric below?
-
- k k k
- A - A + (G - G )A - R A = 0
- j,np j,pn np pn j,k jnp k
