Liouville extension

• we can adjoin integrals and exponentials of integrals + algbraic extension
• an element is said to be representable by a generalized quadrature

 

Picard-Vessiot extension

• examples
  
  • algebraic extension
  • adjoining an integral
  • adjoining the exponential of an integral

 

theorem

If a Picard-Vessiot extension is a Liouville extension, then the Galois group of this extension is solvable.
