Period integrals of hypersurfaces via tropical geometry
Abstract
Let be a one-parameter family of complex hypersurfaces of dimension in a toric variety. We compute asymptotics of period integrals for by applying the method of Abouzaid--Ganatra--Iritani--Sheridan, which uses tropical geometry. As integrands, we consider Poincar\'{e} residues of meromorphic -forms on the ambient toric variety, which have poles along the hypersurface . The cycles over which we integrate them are spheres and tori which correspond to tropical -cycles and -cycles on the tropicalization of respectively. In the case of , we explicitly write down the polarized logarithmic Hodge structure of Kato--Usui at the limit as a corollary. Throughout this article, we impose the assumption that the tropicalization is dual to a unimodular triangulation of the Newton polytope.
