Computing noncommutative global deformations of D-modules
Eivind Eriksen
Let (X,D) be a D-scheme in the sense of Beilinson and Bernstein, given by an algebraic variety X and a morphism O_X -> D of sheaves of rings on X. We consider noncommutative deform…
Connections on modules over singularities of finite CM representation type
Eivind Eriksen, Trond S. Gustavsen
Let A be a commutative k-algebra, where k is an algebraically closed field of characteristic 0, and let M be an A-module. We consider the following question: Under what conditions…
Connections on modules over quasi-homogeneous plane curves
Eivind Eriksen
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…
Computing obstructions for existence of connections on modules
Eivind Eriksen, Trond S. Gustavsen
We consider the notion of a connection on a module over a commutative ring, and recall the obstruction calculus for such connections. The obstruction calculus is defined using Hoch…
