Capitalization of "Subsection" I write a mathematical paper. Do you capitalize "subsection" when you refer to a specific subsection? For example, I would write:

"In Subsection 3 we show ..."


But I would write:

"In the previous subsection we showed that ..."


What is the consensus on that issue?
You've got it right.  Think of it like proper nouns vs. pronouns.  Compare:


  Mr. Jones told me about types of stars; then he explained how they burn hydrogen.


and


  Subsection 3 explains about types of stars; the next subsection explains how they burn hydrogen.
