Hello,

Got few issues with the rendering engine in the site:

- It won’t render LaTeX embedded in the topic of the post. See Solving {\ell}_{1} Regularized Least Squares Over Complex Domain. The “StackExchange” forums do render it.
- It won’t handle
`_`

well in LaTeX Code. For instance this code won’t be rendered:`$$ \arg \min_{x} \frac{1}{2} {\left\| A x - b \right\|}_{2}^{2} + \lambda {\left\| x \right\|}_{1} $$`

. Yet if one removes the underscore,`$$ \arg \min_{x} \frac{1}{2} {\left\| A x - b \right\|}^{2} + \lambda {\left\| x \right\|}_{1} $$`

, it will be rendered (At least this is what I had issues with in the above question).

### Showcase of Clause 2

The code of `$$ \arg \min_{x} \frac{1}{2} {\left\| A x - b \right\|}_{2}^{2} + \lambda {\left\| x \right\|}_{1} $$`

:

$$ \arg \min_{x} \frac{1}{2} {\left| A x - b \right|}*{2}^{2} + \lambda {\left| x \right|}*{1} $$

The code of `$$ \arg \min_{x} \frac{1}{2} {\left\| A x - b \right\|}^{2} + \lambda {\left\| x \right\|}_{1} $$`

:

$$ \arg \min_{x} \frac{1}{2} {\left| A x - b \right|}^{2} + \lambda {\left| x \right|}_{1} $$

Thank You.
