Aktien-, Zins- und Währungsderivatehe involved analytic theory of Laplace and Borel transforms has been avoided. However, the link between the cohomology groups and the Laplace and Borel method is made transparent in examples. This way of presenting the theory is close to that of Malgrange .

Differential Operators and Differential Modulesof . deg . above is . if . ≠ 0 and . = 0 for . > .. In the case . = 0 we define the degree to be −∞. The addition in . is obvious. The multiplication in . is completely determined by the prescribed rule δ. = .δ + .′. Since there exists an element . ∈ . with .′ ≠ 0, the ring . is not commutative. One calls . ..

Formal Local Theory. Here . is an algebraically closed field of characteristic 0. For most of what follows the choice of the field . is immaterial. In the first two sections one assumes that . = .. This has the advantage that the roots of unity have the convenient description .λ with λ ∈ .. Moreover, for . = . one can
