I'm not quite sure if this counts as a bug or a feature but I have the following problem with the
ntheorem package. The theorem title is bold face, which I like, but in math formulas setting some (or all) letters to bold may change the meaning of the mathematical quantities (vectors are bold, scalars are normal etc)
So my question: how can I avoid that the mathematical formulas in the title of the theorem are changed but the rest of the title is still set in bold?
As far as I can see the problem does not occur in the (obsolete) theorem package.
