On rings of differential operators derived from automorphic forms
Atsuhira Nagano
We study linear ordinary differential equations which are analytically parametrized on Hermitian symmetric spaces and invariant under the action of symplectic groups. They are gene…
Period differential equations for families of surfaces derived from 3 dimensional reflexive polytopes with 5 vertices
Atsuhira Nagano
In this article we study the families of surfaces derived from 3 dimensional 5 verticed reflexive polytopes with at most terminal singularity. We determine the lattice structu…
A period differential equation for a family of surfaces and the Hilbert modular orbifold for the field
Atsuhira Nagano
In this article we study the period map for a family of surfaces which is given by the anticanonial divisor of a toric variety. We determine the period differential equation a…
Period differential equations for families of K3 surfaces derived from some 3 dimensional reflexive polytopes
Atsuhira Nagano
We study period maps for families of surfaces those are given by anti canonical divisors of toric varieties coming from reflexive polytopes and . We obtai…
