How to modfiy spacing for inline math?

Question

I want to reduce spacing between operators in inline math. If I add the follwing lines to the peamble it affects both inline and display math modes.

\thinmuskip=0mu
\medmuskip=0mu
\thickmuskip=0mu

How can I limit the effect to inline math without using separate groups for each piece of text?

Answer 1

Are you sure you want the spacing that tight?

You could use \everymath to insert the declarations at the start of every technically inline expression but this will include many build up constructs (arrays, AMS alignments, that use displaymode in inline math.

If you enter inline math using \( rather than $ it is easy you can go

\let\oldmath\(
\DeclareRobustCommand\({%
\oldmath\thinmuskip=0mu
\medmuskip=0mu
\thickmuskip=0mu
}
