[O] latex equations and $ sign

[Federico Beffa]

Hi,

I would like to have a mathematical equation typeset in latex and automatically generated by sympy, embedded in an equation environment:

  #+NAME: mass-energy
  #+BEGIN_SRC python :results raw :exports results :wrap EQUATION
    import sympy as sp
    E, m, c = sp.symbols('E, m, c', real=True, positive=True)
    E = m*c**2
    return sp.latex(E)
  #+END_SRC


  #+NAME: eq:1
  #+RESULTS: mass-energy
  #+BEGIN_EQUATION
  c^{2} m
  #+END_EQUATION

The problem I'm facing is that despite the fact that the equation is already in a mathematical mode latex environment, it still gets sub- and superscripts surrounded by a $ sign. Here is the generated latex snippet:

\begin{equation}
\label{eq:1}
c$^{\text{2}}$ m
\end{equation}

Is there a way to teach org-mode not to insert $ signs in equation environments?

Thanks,

Fede
