Thanks for the link, this will be very helpful, as I'm finding it easier to

I guess your problem here is that you want to use complex conjugate but

Yes it is (in part because you're using an overline character as the
overline - doh! why didn't I think of that?)  However, your code looks fine
in my Firefox window, but FF isn't rendering any of my MathML even close to
correct (I can post a screen shot and my source if that will help).  I
compared your source to mine and there were differences between their
"pre-headers" and their heads, so I changed mine to yours, but no
improvement (for some obscure reason, doing so, in Amaya, "broke" all my
non-breaking spaces in the body, at which point Amaya complained and
wouldn't render anything after the first broken nbs; so I had to go back and
repair those, and then Amaya rendered the source - incl. the new pre-head
and head - fine, but upon refreshing in Firefox, I still saw the same old
text w/out formatting).  Any ideas?

OK, gotchya.

Thank you very much for the help,
