Remove the first bracket and replace it with \ lbrace
$$
\phi_2(x,y)=\left\lbrace
\begin{array}{ll}
1 & \textrm{if x contains 'stock'
and y is 'sport'} \newline
0 & \textrm{otherwise}
\end{array}
\right.
$$
According to GitHub Flavored Markdown Spec, Sec. 6.1
Any ASCII punctuation character may be backslash-escaped:
\!\"\#\$\%\&\'\(\)\*\+\,\-\.\/\:\;\<\=\>\?\@\[\\\]\^\_\`\{\|\}\~
Hence the whole process is
\left\{
and gfm parser uses it as input\left{
and github-mathjax (and mathjax) uses it as input{ is not a delimiter
And, duplicate of #26 .
Sorry, I have not found that this is a so-old issue.
thx
Missing or unrecognized delimiter for \left .
For example, $$ \phi_2(x,y)=\left{ \begin{array}{11} 1 & \textrm{if x contains 'stock' and y is 'sport'}\ 0 & \textrm{otherwise} \end{array} \right.. $$
