Defining a function of one variable to be elementary if it has an explicit representation in terms of a finite number of algebraic operations, logarithms, and exponentials, Liou- ville's theorem in its simplest case says that if an algebraic function has an elementary integral then the latter is itself an algebraic ...
Liouville's theorem states that elementary antiderivatives, if they exist, are in the same differential field as the function.
This talk should be regarded as an elementary introduction to differen- tial algebra. It culminates in a purely algebraic proof, due to M. Rosenlicht.
Liouville's main theorem asserts that if an elementary function f is integrable in elementary terms then there are severe constraints on the possible form of an.
