Hi,
I have been looking around, and I can't seem to find a slightly different version of the lie derivative where the lie derivative is taken with respect to a tensor field, rather than a vector field. That is, a quantity which measures the change in a vector field, along the "flow" of a tensor field.
I am not asking about the lie derivative of a tensor, which is the change in a tensor field through the flow of a vector field.
does such a derivative exist? is this a reasonable question?
Also, would a different, but correct way to describe the Lie derivative be "it measures the change in a tensor field with respect to the change in a vector field" ?
Thanks,
