I use hexo-theme-next for my blog, and I met a problem same with #826.
I wrote a plugin hexo-renderer-markdown-it-plus for fix it,and this article is a demo for hexo-renderer-markdown-it-plus
The hexo default hexo-renderer-marked do not support LaTex parser, you must referer external link to parse Latex grammar to html(That’s whathexo-theme-next did, hexo-theme-next use mathjax), and the mathjax and hexo-renderer-marked will cause some problem:
_parse error, you must changex_itox\_i(This problem had been fixed when i test.)- do not support lines grammar, expample below:
$$
H=-\sum_{i=1}^N (\sigma_{i}^x \sigma_{i+1}^x+g \sigma_{i}^z)
$$
$$
f(n) = \begin{cases}
\frac{n}{2},
& \text{if } n\text{ is even}
\\ 3n+1, & \text{if } n\text{ is odd}
\end{cases}
$$
$$
\begin{aligned}
\nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\
\nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
\nabla \cdot \vec{\mathbf{B}} & = 0 \end{aligned}
