grtensor

[alejandrito20]

I want to calculate the Ricci tensor for a 5-D metric.

 

For example , the randall sundrum metric.

 

ds^2=dw^2+exp(-2A(w))*(-dt^2+dx^2+dy^2+dz^2)

 

there is any computer program to calculate ricci tensor in 5d spacetime?

 

In 4d , using grtensor for the metric:

 

ds^2=exp(-2A(w))*(-dt^2+dx^2+dy^2+dz^2)

 

but, all component are zero (figure)

 

any suggestions?

I did write one in Mathematica a few years ago. Unfortunately, I don't have it anymore.

 

There are packages available for Mathematica out there that will do the job.
