4th rank Tensor

    Hi,

    Can somebody give me an example of a rank 4 tensor in physics?

    Thanks.

    Sure, one would be the Riemann curvature tensor Rijkl that's used in general relativity.

    Thanks.

    It was an odd small part of an exam question when my module had only covered examples up to 3rd rank.

    Third order nonlinear susceptibility is another example of 4th rank tensor.
