Abstract: |
We construct an action of a Kac-Moody Weyl group on the totality of Fuchsian differential equations and give a universal model of the equations with a given spectral type. Moreover we obtain explicit connection coefficients for the rigid Fuchsian differential equations and give a unified interpretation of confluence, contiguity relation for ordinary differential equations together with its generalization to partial differential equations. The integral representation and series expansion of their solutions are also within our interpretation. |
