  • differential galois theory
  • Liouville 

 

 

historical origin
  • integration in finite terms
  • quadrature of second order differential equation (Fuchsian differential equation)

 

 

differential field
  •  

 

elementary extension
  • using exponential and logarithm
  • elementary element

 

 

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
  • this corresponds to 
  • 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.

 

 

Fuchsian differential equation
  • regular singularity
  • indicial equation
    \(x(x-1)+px+q=0\)
     

 

solution by quadrature
