Here are three possible approaches that you might try.


1.  Try reducing the space between words, as in:

   Exceptional\,Rational\,Functions: Degree = 1


2.  Put in an explicit kern:

   Exceptional Rational Functions:\kern-3pt Degree = 1

where you can tinker with the amount to

  a.  allow a tiny overflow into the right margin ;

  b.  but not too much to prevent the line-break being
      where you want it to be.


3.  Use a negative  \penalty  to make the breakpoint
     more attractive:

   Exceptional Rational Functions:\penalty-50 Degree = 1


The latter is probably the best, as it will encourage TeX
to squeeze up any flexibility in the interword spaces
to get the whole line to fit, if at all possible.


A possible draw-back of these approaches is that the extra
markup might make it into the .toc file and PDF bookmarks.
So some extra effort is needed to clean up these automatically
generated entries.

Hope this helps,
