Grtensor 5d?

    grtensor 5d???

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

    For example , the randall sundrum metric.


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

    In 4d , using grtensor for the metric:


    but, all component are zero (figure)

    any suggestions?

    grtensor will do it - just do "makeg your_metric_name" and define your line element - it's not restricted to any fixed number of dimensions.

    then do grcalc(Ricciscalar);
