    What are you trying to do in the first place? What mathematical object is S suppose to be.

You need nolimits to force mathop not to treat the operator like, for example, sum.

    Of course the question arises whether we are talking about an operator (in TeX speak, not necessarily mathematically) here in the first place. Maybe letorigSSrenewcommandSifmmodemathsfSelseorigSfi would be more sensible.

Assuming your command should be a mathop, the correct redefinition would be



renewcommandmathsection{operatornamemathsfS


Redefining S that way is bound to problems, as S is a “robust” command.



If it is not an operator, renewcommandmathsectionmathsfS would suffice.



You can see the difference in the two examples below (twocolumn used just for making a smaller picture). In (1) the symbol behaves like an operator, in (2) it's an ordinary symbol.

            One-line joke

            A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain.
