Hi,
 
I am trying to copy latex code generated by Sage to Lyx. It seems Sage generates additional curly braces around (). For example, with:
 
sage: latex((alpha^2-alpha)*theta)
 
I get:
 
{\left(\alpha^{2} - \alpha\right)} \theta
 
If I paste this code to Lyx math, then there are unnecessary {} around the () showing.
Maybe it's LyX's problem since if I paste it to an .tex source and compile it then it does not show. However I already have a long document in LyX so it would be great if there is any way to get rid of {}.
 
Thank you!

I think you may be right about it being LyX's problem.  We recently removed something like this for multiplication (see http://trac.sagemath.org/sage_trac/ticket/11415), not sure whether removing this would break something else.

Correct me if I'm wrong - the braces do not appear in the compiled pdf/dvi, so why do they bother you?

@parzan - So you are saying that it shows up in the Lyx source code, but the Lyx compiled document does not have them?

@krisman @parzan is right. I never actually tried to compile it in LyX. I just tried that and the extra braces are not showing in the pdf, even though lyx is showing it.

You can see that these braces appear in red in LyX - this means that they only serve as a container. I recommend running LyX with Preview:on (in Pref. -> Look&Feel -> Display) - you then see immediately how the latex compiles (you might need to restart after enabling it).
