I have a very long equation
\begin{equation*}
\begin{aligned}
multiple line equation...
\end{aligned}
\end{equation}
But just using the above code causes the whole equation to start from a new page leaving behind a third of previous page empty.
Where should i put the \displaybreak command to ensure that the page breaks occurs conveniently in between the equation.
I tried using it in the following manner but it doesn't help.

\allowdisplaybreak
\begin{equation*}
\begin{aligned}
multiple line equation...
\end{aligned}
\end{equation}

The point is that, aligned environment wraps its contents inside an unbreakable box. So, these commands (that is, both
\displaybreak
and\allowdisplaybreaks
) do not have any effect.This is true of
split
,gathered
andalignedat
environments too.So, to get the line break to work, you might consider using
align*
, as suggested by egreg.You might want to refer to
amsldoc
, towards the end of page 6 for these comments. I'd also like to draw your attention to the section 3 of this document for discussions regarding display math.By the way, please note that, you have
s
missing in\allowdisplaybreaks
.
