Ellis Kolchin developed differential Galois theory in the 1950s. It seems to be a powerful tool that can decide the solvability and the form of the solutions to a given differential equation.



Why isn't differential Galois theory widely used in differential geometry? It is plausible that we can solve some problems of differential/integral geometry using this theory.



So, what is the major pullback in this theory that prevents its wide application to other fields rather than discrete geometry (e.g., Diophatine geometry)?

    I haven't had much exposure to Galois theory yet, but I have heard that it is not widely taught, so I conjecture that the teachers of these courses aren't sufficiently comfortable with it.

    @Incurrence The question is about differential Galois theory, not ordinary (algebraic) Galois theory, and it's about research in differential geometry, not courses. When you write "I have heard that it is not widely taught" and "the teachers of these courses aren't sufficiently comfortable with it", if you're talking about algebraic Galois theory, you're wrong on both counts.
