Here is what I have typed:

\begin{equation*}
s_j=\frac{e_j}{\min_{1 \leq k \leq m-1} \big\{t_{jk} + t_{j(k+1)} \big\}
\end{equation*}

however, it is displaying as a subscript rather than UNDER the min operator.

Is this because the operator is in the denominator?

How do I fix this?

thanks :)

    Welcome to TeX.SE. Try adding \limits_ after the \min. For future reference, while code snippets are useful in explanations, it is always best to compose a fully compilable MWE that illustrates the problem including the \documentclass and the appropriate packages so that those trying to help don't have to recreate it. – Peter Grill Apr 19 '17 at 8:37
  • @PeterGrill thanks for the heads up :) I will add the preamble bit next time. The course I'm taking requires us to learn how to use LaTex. They've given us an assignment template that has the preamble already done. However, I've had to add some packages. – sarah jamal Apr 19 '17 at 9:09

TeX forces the scriptstyle when typesetting denominators in display math.

This way the min operator loses the limits, which are typeset in a nolimit way.

I suggest to typeset \limits as suggestd by PeterGrill:

\documentclass{article}
\usepackage{amsmath}

\begin{document}
    \begin{equation*}
    s_j=\frac{e_j}{\min\limits_{1 \leq k \leq m-1} \big\{ t_{jk} + t_{j(k+1)} \big\}}
    \end{equation*}
\end{document}

Producing:

As correctly remarked by @Thurston, you can also achieve a similar using the \displaystyle cmmand, which yields the same result here, but it's not recommended since it changes all of the group style. Anyway here it is:

\documentclass{article}
\usepackage{amsmath}

\begin{document}
    \begin{equation*}
    s_j=\frac{e_j}{\displaystyle\min_{1 \leq k \leq m-1} \big\{ t_{jk} + t_{j(k+1)} \big\}}
    \end{equation*}
\end{document}

Outputting:

  • You could also force it into display style with ...{\displaystyle\min_{... – Thruston Apr 19 '17 at 9:00

    @Moriambar Better \limits. – egreg Apr 19 '17 at 10:13
  • @egreg since it won't change the rest of the styles? – Moriambar Apr 19 '17 at 10:14
  • @Moriambar Yes, indeed. – egreg Apr 19 '17 at 10:15
