Hello:
I have a doubt because I don't find the general definition of the nabla operator in order to solve my matter.
I am working with dyadic analysis and I have to prove that
[tex]\nabla^{2}F = \nabla \nabla \bullet F[/tex]
where F is a symmetric dyadic function.
My problem is when I have to get [tex]\nabla^{2}F[/tex]
because I don't know how to calculate the gradient of a dyadic. I know the definition of the gradient of a vector what results in a dyadic, but no idea about the general definition of the gradient in cartesian coordinates for whatever order of cartesian tensors.
I 'd be very thankful for a little of help.
