I'm surprised you can use \textsc in math mode without getting an error message. I would have thought of only two ways to use small caps text in math:

- Based on the information in /usr/local/teTeX/share/texmf.tetex/doc/latex/base/fntguide.dvi, define a new math alphabet \mathsc. For example:


and then you can write for example $\mathsc{l}$.

- By loading the amsmath package and using the command \text that it defines, for example $\text{\textsc{l}}$.

I would rather attribute this to the use of a text command like \textsc in math mode.

\boldsymbol should be used as $\boldsymbol{((}$ (it's a command taking an argument, not a declaration like \boldmath). In your case, in ${\boldsymbol ((}$, the braces { and } are ignored, the first "l" is interpreted as the argument of \boldsymbol and the second "(" isn't affected.

In any case the command \boldsymbol, as defined by the amsmath package, is deprecated, and the AMS recommands now using the standard package bm defining the command \bm to be used as $\bm{((}$. See /usr/local/teTeX/share/texmf.tetex/doc/latex/tools/bm.dvi. If my memory is correct, \bm switches automatically to poor man's bold in case no matching bold face exists.
