code:

$\begin{aligned}
\max & c \cdot x
\\\\
s.t. & A_{m_1 \cdot n} \cdot x \le b
\\\\
& Aeq_{m_2 \cdot n} \cdot x = beq
\\\\
& x_i \ge 0
\end{aligned}$

and the result is like this:

<p>$\begin{aligned}
\max &amp; c \cdot x
\\
s.t. &amp; A<em>{m_1 \cdot n} \cdot x \le b
\\
&amp; Aeq</em>{m_2 \cdot n} \cdot x = beq
\\
&amp; x_i \ge 0
\end{aligned}$</p>

when the Aeq line is removed the em tag disappears and everything is normal.

That's a typical side-effect of mixing markdown with TeX-like input. The best way to work around this is to replace math content with placeholders before markdown conversion happens and place it back at the placeholders afterwards. If the markdown converter tolerates inline HTML well (e.g., no forced line-breaks), then pre-processing into MathML (e.g., using MathJax-node) before the markdown conversion should also do the trick.
