Math & Science ⇒ Bad math environment delimiter, please help

[stephencrowley]

Can someone please tell me what is wrong with the following snippet? It was generated by exporting latex from TeXmacs.

Code: Select all

$\begin{equation}
  \begin{array}{ll}
    \begin{array}{l}
      _p F_q \left( \begin{array}{l}
        a_1, \ldots, a_p\\
        b_1, \ldots, b_q
      \end{array} | t \right)
    \end{array} & = \sum_{k = 0}^{\infty} \frac{t^k}{k!} \frac{\prod_{i = 1}^p
    (a_i)_k}{\prod_{j = 1}^q (b_j)_k} \label{hypergeom}
  \end{array}
\end{equation}$

Thanks,
Stephen

Hi Stephen,

welcome to the board!

Nice to hear that TeXmacs still has users. I did not see progress there for some time.

Here, the problem is simply that the equation environment starts math mode itself, so you should not start (and end) inline math mode by $. Just remove the two $ symbols.
