Re: [Maxima-discuss] Correct Syntax for Greek Letters in Maxima Batch Files for LaTeX Export

[Jaime V. <vi...@fe...>]

The reason why x^y is typeset as you expect in LaTeX and x_y not, is 
because ^ is a Maxima operator while _ is not. Maxima sees x^y as two 
symbols with the infix operator ^ between them, but x_y as a single 
symbol with name x_y (sigma_x is then a valid symbol name, different 
from sigma):
