Abstract
Let k be an algebraically closed field of characteristic 0, and let be a quasi-homogeneous plane curve. We show that for any graded torsion free A-module M, there exists a natural graded integrable connection, i.e. a graded A-linear homomorphism that satisfy the derivation property and preserves the Lie product. In particular, a torsion free module N over the complete local ring admits a natural integrable connection if A is a simple curve singularity, or if A is irreducible and N is a gradable module.
