This is not important, but some math equations do not display correctly
For some obscure reason, math equations that seem to have a perfectly correct TeX syntax do not appear correctly on my browser (Firefox; I just see the TeX line instead) ; I have seen it today on Hilbert space, and it was probably the reason why some anonymous editor tried to fix the formula; another user reverted to the previous version (correct syntax, but I don't see it correct). Once I fixed this on my screen by the silly solution of adding spaces (ignored by TeX) at both ends of the formula. A solution? Bdmy (talk) 22:37, 17 November 2008 (UTC)
