Usage of \operatorname{span} instead of "span"

[kulla]

In formulas we want to write \operatorname{span} instead of span.

@kulla Could you give an example for the usage of span? Are html-spans allowed in formulas?

[kulla]

I meant this span ("lineare Hülle / Erzeugnis"): https://de.wikibooks.org/wiki/Mathe_f%C3%BCr_Nicht-Freaks:_Spann,_Erzeugnis,_lineare_H%C3%BClle#Definition_des_Spanns :-)

Ah, thanks.
