I'm currently typing a mathematical document which counts many sum
symbols. I frequently use the align
environment to render equations, although the default behaviour of this environment is to render the equations in displaystyle
, which in my opinion wastes vertical space. I therefore have added \textstyle
at the beginning of each line of math in this environment, but I'm looking for a more convenient solution.
So is there an environment that is similar to align
with the exception it displays textstyle
math by default ? Thank you.

Not sure what the usage for this is, but here's a possible way to go; it is based on the fact that in each cell of
align
a\displaystyle
declaration is issued; of course this has severe limitations, because\dfrac
will not work, for example.If you want to be able to use
\displaystyle
in the subformulas, then a more complicated approach is needed: the command\displaystyle
is locally defined to issue\textstyle
and to redefine itself to be the primitive\displaystyle
.
