- 1.5: Cartan's Uniqueness Theorem
- Cartan's uniqueness theorem is another analogue of Schwarz’s lemma to several variables. It says that for a bounded domain, it is enough to know that a self mapping is the identity at a single point to show that it is the identity everywhere. As there are quite a few theorems named for Cartan, this one is often referred to as the Cartan's uniqueness theorem. It is useful in computing the automorphism groups of certain domains.
