If one doesn't like _ and ^ one can always do this \def\sub{_} \def\sup{^} $\sum\sub{i=0}\sup p a\sub i y\sub{n-i} = \sum\sub{l=0}\sup q b\sub i \xi\sub{n-i}$ which might look better with full braces $\sum\sub{i=0}\sup{p} a\sub{i} y\sub{n-i} = \sum\sub{l=0}\sup{q} b\sub{i} \xi\sub{n-i}$ Looks even better than eqn to me since you can tell which scripts belongs to which symbols. What's the big deal?
