Embedding Problem

Liouville's Theorem (differential Algebra) - Relationship With Differential Galois Theory
... Liouville's theorem is sometimes presented as a theorem in differential Galois theory, but this is not strictly true ... The theorem can be proved without any use of Galois theory ... Furthermore, the Galois group of a simple antiderivative is either trivial (if no field extension is required to express it), or is simply the additive ...
