M. Passare et al., MULTIPLE MELLIN-BARNES INTEGRALS AS PERIODS OF CALABI-YAU MANIFOLDS WITH SEVERAL MODULI, Theoretical and mathematical physics, 109(3), 1996, pp. 1544-1555
We give a representation, in terms of iterated Mellin-Barnes integrals
, of periods on multi-moduli Calabi-Yau manifolds arising in superstri
ng theory. Using this representation and the theory of multi-dimension
al residues, we present a method for analytic continuation of the fund
amental period in the form of a Horn series.
