TeX - LaTeX Asked on August 26, 2021
If a short line is followed by an align
environment then the spacing between the aligned content and the text above it is too large (in my opinion). See the spacing above x = y_i
in the example. The standard display environment [ ]
seems to adjust this spacing depending on the length of the preceeding line, but align
doesn’t seem to do this.
Is there a way for
align
to make the space atop of it depend on the length of the preceeding line (like[ ]
does)?

usepackage{mathtools}
begin{document}
begin{minipage}[t]{0.45textwidth}
begin{center}
texttt{align*}
end{center}
text text text text text text text text text
begin{align*}
x &= y_i
shortintertext{text}
x &= z_{i+1}
end{align*}
text text text text text text text text
end{minipage}
hfill
begin{minipage}[t]{0.45textwidth}
begin{center}

end{center}

[
x = y_i

[
x = z_{i+1}
]

end{minipage}
end{document}
As explained in the comments and in the mathtools
manual (section 3.1.5) this is a problem that some of the AMS environments have.
The mathtools
package provides the command SwapAboveDisplaySkip
to fix this problem manually.

SwapAboveDisplaySkip % less space
