How do you capitalize the titles of references in a math paper? Would you rather write:
Global smooth solutions of the Navier-Stokes equations
Global Smooth Solutions of the Navier-Stokes Equations
? The latter capitalization is the usual capitalization, where every non-grammatical word, and all names, are capitalized. But the former variant seems to be common in the references. The only exception seem to books, which are usually capitalized as on their titles.
I have been skimming over the list of references in mathematical papers by well-regarded researches, but I have not found a definitive pattern. In fact, in many publications, neither the author nor the editor seems to actually care.
