How to use this knowledge base

Written for doctoral students and postdocs: compact statements you can reuse in prelims, papers, and seminars—not a first undergraduate course.

How to read a page

  1. Job — why the notion exists in research
  2. Core — definitions + main theorems (hypotheses matter)
  3. See it — a standard non-toy example
  4. Check — proof-level or counterexample self-test
  5. Next / Refs — continue or open a monograph

Undergrad-titled pages (arithmetic, school algebra, …) are recall cards, not lessons.
