Abstract: | We study Abelian integrals associated with a tame polynomial function and their Picard–Fuchs equations using the theory of
algebraic Gauss–Manin systems. Especially, we look for a basis of the Petrov module, in which the Picard–Fuchs equations become
as simple as possible. As an application, we discuss the related Riemann–Hilbert problem and prove that it has a positive
answer under some conditions. In this case, we compute the Jordan normal form of the residue matrices of the corresponding
Fuchsian system in terms of local data.
