Contradiction on the invariant chart: local context

Project map · Chapter map · Full theorem DAG · Open textbook statement

This local map shows one dependency hop in either direction. The highlighted item is the current focus.

fully proved2Proved, and every prerequisite is fully proved too.ready to state1Nothing it needs is blocked, so the statement can be written in Lean.planned9Described in the blueprint only.
