Outline of Final Research Achievements |
We can interpret differential Galois theory as a theory of Module algebras under the Hopf algebra of the co-orrdinate ring of the 1 dimensional additive group. Hopf algebraists succeeded in generalizing the theory of linear equations from this view point, to a co-commutative Hopf algebra acting on a commutative module algebra. There arises a natural question whether we can extend this general theory to non-commutative case, or we can quantize it. Using the notion of Galois hull born in our study of Galois theory of non-linear differential equations, we successfully established a general Galois theory of non-commutative linear equations with constant coefficients.
