It's a standard notation in tensor analysis.

Thank you. I was reading that as raised to the power. I am familiar with
the superscript notation in tensor analysis. I just didn't catch on that
you were using ^ to indicate it. In Mathematica it means 'raised to the
power of', and I guess force of habit blinded me to the obvious. I probably
should have waited till the first cup of coffee kicked in before I posted.

Ascii sucks a bit. In this group are variations
like dx^1 = dx, dx^2 = dy , dx^3 = dz,
sometimes people use dx2 == dx*dx,
there are no *official* standards so I usually
understand the context, or, as you did ask
for clarification, hang around it'll grow on ya.
