Gullstrand-Painleve/Doran articles with bad Latex?

    I've been intrigued for some time by the following posts, but they all have lots of Latex errors (at least for me, Firefox/Linux).

    Can anyone confirm they are broken before I make an idiot of myself in a PM, and in any case is it appropriate to PM for this sort of thing?

    I see a lot of broken Latex with FireFox

    dt\,+\,\frac{\beta}{1-\beta^2}\,dr&=&d\bar{t}&=& &d\breve{t}-\,\frac{1}{1+\beta}\,dr\\[6mm]
    d\phi\,+\,\frac{\beta}{1-\beta^2}\,\frac{a}{(r^2+a^2)}\,dr&=&d\bar{\phi}&=& &d\breve{\phi}\,-\,\frac{1}{1+\beta}\,\frac{a}{(r^2+a^2)}\,dr
    This is it fixed.
    dt\,+\,\frac{\beta}{1-\beta^2}\,dr&=d\bar{t}= d\breve{t}-\,\frac{1}{1+\beta}\,dr\\
    d\phi\,+\,\frac{\beta}{1-\beta^2}\,\frac{a}{(r^2+a^2)}\,dr &= d\bar{\phi}= d\breve{\phi}\,-\,\frac{1}{1+\beta}\,\frac{a}{(r^2+a^2)}\,dr

    Heh, I am already using those equations, they seem to work just fine ;) I just wanted to see how he puts it all together, it sounded interesting, and not too far above my level. BTW it looks just as broken in Chrome.
