 how can i make an arrow with two top? i have to insert it ON a character...
 it is the tensor symbol... thanks...

If you need an arrow over a _single_ character, use
\stackrel space \Rightarrow down X
where X is the character.
You can define a math macro for faster typing.

If you need the arrow over several chars, then use the attached
fill.sty package (put \usepackage{fill} in the preamble),
and use \overbrack{xy} in the formula
(you only need to write \overbrack{xy as lyx automatically adds the
closing } )
