\begin{align*}
\begin{array}{c}
\min \: A = \min \: \sum_{i\in B} C_i
\\ \\
\min \: D = \min \: \sum_{i\in B} \pi_i \cdot F_i
\end{array}
\end{align*}
How can I get i \in B
below the \sum
symbol without breaking the align
into multiple aligns?
Best Answer
By putting a
\displaystyle
in front of the\sum
. You basically want the font to behave like it does in a top-level environment, because it's nested in an array it gets assigned a\textstyle
font size.Why you're not aligning the equations on the equals sign beats me though. It might be better to use two
equation
environments in this case, the code wouldn't look so bloated as it does now.
