Dynamics of modular vector fields, Dwork family, and applications

About

This is a research plan for a collaborative work involving colleagues from Brazil, France and Portugal. Namely, the members of this project are the following: Brazil: H. Movasati (IMPA) and Y. Nikdelan (UERJ); France: J. Rebelo (IMT) and D. de la Rosa (IMT - graduate student); Portugal: H. Reis (UP). Among previous works directly related to the questions raised in this project, we may quote: [G], [AMSY], [RR], [Mov3], and [MN]. Ultimately the purpose of our project is to conduct a dynamical study of certain differential equations appearing in Mathematical-Physics (especially in Mirror Symmetry) as well as in some other contexts, including representations of $\mathfrak{sl}_2(\C)$ and Number Theory. We believe that a good dynamical understanding of the mentioned equations will have a few interesting applications, not least to the study of certain families of Calabi-Yau manifolds along with corresponding Mirror maps.   References: [AMSY]  M.
