Discussion Overview

The discussion revolves around the LaTeX code for representing the upper sum in mathematical notation. Participants share different formatting options and styles for presenting the supremum symbol within the context of upper sums.

Discussion Character

  • Technical explanation

Main Points Raised

  • Dan provides LaTeX code for the summation symbol and the supremum notation, suggesting that \sum_{j \in J} and \underset{x \in B_j} {sup} are appropriate representations.
  • Another participant suggests an alternative formatting using [FONT=courier new]\sup_{x\in B_j}, which results in the supremum symbol appearing in Roman type instead of italics.
  • Peter expresses gratitude to Dan and Opalg for their contributions.

Areas of Agreement / Disagreement

There is no explicit consensus on a single preferred LaTeX representation, as multiple formatting options are presented without resolution.

Contextual Notes

The discussion does not address potential limitations or assumptions regarding the context in which these LaTeX codes are used.

Is this what you want?
\sum_{j \in J} --> [math]\sum_{j \in J}[/math]

and
\underset{x \in B_j} {sup} -->[math]\underset{x \in B_j} {sup}[/math]

-Dan
 
Alternatively, \sup_{x\in B_j} --> $\displaystyle \sup_{x\in B_j}$. (The symbol for sup then appears in Roman type rather than italics.)
 
My thanks to Dan and Opalg …
