Hori-Vafa mirror periods, Picard-Fuchs equations, and   Berglund-H\"{u}bsch-Krawitz duality
  This paper discusses the overlap of the Hori-Vafa formulation of mirror symmetry with some other constructions. We focus on compact Calabi-Yau hypersurfaces \mathcal{M}_G = {G = 0} in weighted complex projective spaces. The Hori-Vafa formalism relates a family {\mathcal{M}_G \in WCP^{m-1}_{Q_1,...,Q_m}[s] | \sum_{i=1}^m Q_i = s} of such hypersurfaces to a single Landau-Ginzburg mirror theory. A technique suggested by Hori and Vafa allows the Picard-Fuchs equations satisfied by the corresponding mirror periods to be determined. Some examples in which the variety \mathcal{M}_G is crepantly resolved are considered. The resulting Picard-Fuchs equations agree with those found elsewhere working in the Batyrev-Borisov framework. When G is an invertible nondegenerate quasihomogeneous polynomial, the Chiodo-Ruan geometrical interpretation of Berglund-Huebsch-Krawitz duality can be used to associate a particular complex structure for \mathcal{M}_G with a particular Kaehler structure for the mirror \widetilde{\mathcal{M}}_G. We make this association for such G when the ambient space of \mathcal{M}_G is CP^2, CP^3, and CP^4. Finally, we probe some of the resulting mirror Kaehler structures by determining corresponding Picard-Fuchs equations.
