Non commutative geometry and super Yang–Mills theory

We aim to connect the non commutative geometry “quotient space” viewpoint with the standard super Yang Mills theory approach in the spirit of Connes–Douglas–Schwartz and Douglas–Hull description of application of noncommutative geometry to matrix theory. This will result in a relation between the parameters of a rational foliation of the torus and the dimension of the group U(N). Namely, we will be provided with a prescription which allows to study a noncommutative geometry with rational parameter p/N by means of a U(N) gauge theory on a torus of size Σ/N with the boundary conditions given by a system with p units of magnetic flux. The transition to irrational parameter can be obtained by letting N and p tend to infinity with fixed ratio. The precise meaning of the limiting process will presumably allow better clarification.
