     My friend told me that in LaTeX, it's like this:

\stackrel{\Rightarrow}{T}

to put the double arrow on top of T.  But if the symbol is longer, like
T_0, the length of the arrow isn't increased, as shown by the example
file attached in this mail.  I don't know any "orthodox" way to write a
tensor, unfortunately.

     For the rest of the mail, I'll look at them later and answer you
soon.
