We give a representation, in terms of iterated Mellin-Barnes integrals, of periods on multi-moduli Calabi-Yau manifolds arising in superstring theory. Using this representation and the theory of multidimensional residues, we present a method for analytic continuation of the fundamental period in the form of Horn series.

Multiple Mellin-Barnes integrals in Schwinger-DeWitt technique
Series expansions are obtained for multiple Mellin-Barnes integrals representing basis kernels in the Schwinger-DeWitt asymptotic expansions of operator functions, with separate treatments for non-resonant and resonan...
