Liouville's theorem

Liouville's theorem has various meanings, all mathematical results named after Joseph Liouville:

*In complex analysis, see Liouville's theorem (complex analysis).
*In conformal mappings, see Liouville's theorem (conformal mappings).
*In Hamiltonian mechanics, see Liouville's theorem (Hamiltonian).
*In number theory, the theorem that any Liouville number is transcendental, "or" the lemma involved on diophantine approximation.
*In differential algebra, a theorem which allows one to determine when a given elementary function has no elementary integral, see Liouville's theorem (differential algebra)
