The latter is based upon the construction and study of the tensor product of non commutative connections over a commutative base, without any curvature assumption. This theory provides an algebraic frame for the study of the confluence arising when the increment of a difference equation tends to 0.65 pagesGeneral MathematicsCommutative AlgebraQuantum Algebra12H05, 12H10, 12H20, 13N05, 13N10, 34M15, 81Q70, 18D10, 53C, 46LDifférentielles non commutatives et théorie de Galois différentielle ou aux différencestext
