Divergence of Gradient inverse

  1. Jan 11, 2016 #1
    Dear All,

    I'm doing some tensor calculation on the divergence of gradient (of a vector) inverse. Am I allowed to first use the nabla operator on gradient and then inverse the whole product?
    In other words, I'm searching for the divergence of a 2nd order tensor which is itself inverse of (gradient of a first order tensor ). Thanks in advance

    What do you mean the inverse gradient?

    Is it something like [tex] \frac{1}{\nabla} \phi [/tex]?
