I am trying to write multiple lines underneath my minimisation problem in an align* environment. This can be achieved by using the command \min_{\substack{x_{j} \\ j=1,...,70}}, which produces the following output

enter image description here

I would like to write minimisation, as opposed to min. However, the command \textnormal{minimise}_{\substack{x_{j} \\ j=1,...,70}} does not produce the required output. How can this be achieved?

  • The number of left and right curly braces in your expression don't match.

    @inavda This should now be fixed. Thanks.

    Off-topic: I would replace j=1,...,70 with j=1,\dots,70 in order to get a proper typographic ellipse.

From some quick experimentation, using \operatorname* instead of \textnormal seems to do the trick.
