Cover Letter to the Editors (anmath-cover-letter)

When to trigger

• The manuscript is final and you are preparing the submission package
• You need a short note conveying significance and scope fit to the editor
• There is prior work, an arXiv posting, or overlap that should be disclosed up front

First verify on the official submission page whether a cover letter is expected and in what form. Some math journals want a brief note; others collect the same information in the portal. Keep it short either way — the paper carries the weight.

What an Annals cover letter does

The editors triage on importance and fit. The letter's job is to let an editor see, in under a page, why this result clears the Annals bar and which area it belongs to — not to re-prove anything.
