Abstract:
The paper deals with residue representations of $n$–dimensional Mellin transforms for rational functions with quasi-elliptic denominators. These representations are given by integrals over $(n-1)$-dimensional relative cycles. The amount of representations (or cycles) equals to the number of facets of the Newton polytope for the denominator of the rational function.
Keywords:
multidimensional Mellin transform, quasi-elliptic polynomial, Leray residue form, amoeba.
