Discussion Overview

The discussion revolves around formatting a mathematical expression in LaTeX, specifically how to position the constraint "1 ≤ m ≤ M" directly under the "arg" notation in an inline expression. Participants explore various formatting options and clarify the context of their needs.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant asks how to position "1 ≤ m ≤ M" directly under "arg" in a LaTeX expression.
  • Another participant suggests using I=\mathop{\mbox{arg}}_{1\le m \le M} as a potential solution.
  • A later reply indicates that the suggested code did not work for the original poster because the expression is intended to be inline.
  • One participant proposes using I=\displaystyle{\mathop{\mbox{arg}}_{1\le m \le M}} to force the positioning, noting it adds extra spacing.
  • Another participant questions the necessity of using "arg" instead of "argmin" or "argmax," suggesting that the context might be better served with those terms.
  • The original poster clarifies that they need the argument of an arbitrary value m, not the minimum or maximum values.

Areas of Agreement / Disagreement

Participants express differing views on the appropriateness of using "arg" versus "argmin" or "argmax," indicating a lack of consensus on the terminology. There is also no agreement on the best formatting solution, as some suggestions did not meet the original poster's needs.

Contextual Notes

The discussion highlights the challenges of formatting inline expressions in LaTeX and the specific requirements of the original poster, which may not align with standard practices for "arg" notation.

Hello

In the following, I need [tex]1\leq m\leq M[/tex] to be exactly under "arg", How can I do that?

[tex]I=\text{arg}_{\substack{1\leq m\leq M}[/tex]

Thanks in advance

How about this:

Code:
I=\mathop{\mbox{arg}}_{1\le m \le M}

which gives:

[tex]I=\mathop{\mbox{arg}}_{1\le m \le M}[/tex]

Thanks alphysicist for replying, but the code you gave did not work in my case. I forgot to mention this expression is an in-line expression, I don't know if this has anything to do with the problem.

Best regards

You can force it by using displaystyle:


Code:
I=\displaystyle{\mathop{\mbox{arg}}_{1\le m \le M}}

but of course that will put extra spacing between the lines of your text.
 


Why do you want this to appear under "arg" anyway? If you want the minimum or maximum value over a range of arguments, then it would be underneath "min" or "max," and if you want the argument that results in the minimum or maximum of the expression, then it should be "argmin" or "argmax", but what the heck is just "arg" ?

Yes, now it works. Thanks a lot.

I neither want the argument of max nor min values, I need the argument of an arbitrary value m. Of cource, I didn't write the whole expression because it doesn't affect what I want.
