Does anyone know if it is possible define a metric like the metric below?

 

 

Thanks in advance!

Hello everyone!

I am trying to calculate the Killing vectors for the metric below. For such, I used the packages DifferentialGeometry and Physics. However, I found different results these packages. Could someone explain why?

Thanks in advance!

killing_test1.mw

killing_test2.mw

 

Could anyone explain why Maple doesn't calculate the Killing vectors for the metric below?

Thanks in advance!

killing2.mw

Could anyone tell me why Maple changes the sign of some expressions? For example...

I would like the outputs to be that way.

sqrt(r/(r-b))

How to prevent this changes?

Thanks in advance,

 

Denis
