produces a lot more space on both sides of the "<" than around the "?"
--- is that normal? I can fix it adequately with this
but even that has slightly more space around the "<" than around the
"?". Is there a right way to make them match?
For consistency, one should always have the same space around
all relation symbols. The space that TeX uses for this is
called \thickmuskip, normally set to "5mu plus 5mu" (a stretchable
You can set \thickmuskip = 0mu to make it disappear completely
from all relation symbols. This is almost certainly a bad idea
as it can confuse a reader trying to parse your formulas
The unit "mu" that is used for this space has a value of
one-eighteenth of a \quad. It is defined this way so that it
will automatically adjust to being used in subscripts, where
the fonts and therefore the \quad, are smaller.
In very rare circumstances one might want a one-time use of
a smaller space. In this case Ulrike's solution can be used.
The braces causes 0mu of space to be used (usually). You can
then manually add a little more if that is too cramped.
