Same with \displaystyle\prod_{n\in\mathbb{Z}}

Is this only a problem for \sum and \prod, or are there further symbols that should use under instead of sub in display style mode?

@SalixAlba should we start with those two, or is there a more complete list?

We get the same for

\bigcup_{n>k} J \quad \biguplus_{n>k} L \quad \bigcap_{n>k} N
\bigoplus_{n>k} W \quad \bigotimes_{n>k} V \quad \bigodot_{n>k} F
\bigvee_{n>k} V \quad \bigwedge_{n>k} W \quad \bigsqcup_{n>k} S

\coprod_{n>k} RR is another case

The following operators from the amsopn package should also have limits typeset below them in \displaystyle:

• \min, \max, \sup, \inf
• \injlim, \varinjlim, \lim, \varliminf, \liminf, \limsup, \varlimsup, \projlim, \varprojlim
• \det, \gcd, \Pr

For your convenience, here's the list again, ready for pasting into LaTeX:

\min_x
\max_x
\sup_x
\inf_x
\injlim_x
\varinjlim_x
\lim_x
\varliminf_x
\liminf_x
\limsup_x
\varlimsup_x
\projlim_x
\varprojlim_x
\det_x
\gcd_x
\Pr_x

Currently failing for

\bigvee_{n>k} V \quad \bigwedge_{n>k} W \quad \bigsqcup_{n>k} S

With conditions by rhs

\int_{n>k} U \quad \oint_{n>k} T \quad \iint_{n>k} S

Conditions should be by RHS.

All the cases Dexxor mentioned fail. There is a related bug with \varliminf_x \varlimsup_x with too small lines above and below.

@SalixAlba @Dexxor thank you.

Do we already have a phabricator ticket for that?

@Andreg-p I invite you to review

https://gerrit.wikimedia.org/r/c/mediawiki/extensions/Math/+/1083469

that looks like that

for the input given by @Dexxor and some additional new lines.
