On 3-lattices and spherical designs
Junichi Shigezumi
An integral lattice which is generated by some vectors of norm is called -lattice. Classification of 3-lattices of dimension at most four is given by Mimura (On 3-lattice, 2…
A note on zeros of Eisenstein series for genus zero Fuchsian groups
Junichi Shigezumi
Let be a genus zero Fuchsian group of the first kind having as a cusp, and let be the holomorphic Eisenstein series associ…
A construction of spherical designs from finite graphs with the theory of crystal lattice
Junichi Shigezumi
We want to introduce a construction of spherical designs from finite graphs with the theory of crystal lattice. We start from a finite graph, and we consider standard realization o…
On the zeros of certain modular functions for the normalizers of congruence subgroups of low levels II
Junichi Shigezumi
We research the location of the zeros of the Eisenstein series and the modular functions from the Hecke type Faber polynomials associated with the normalizers of congruence subgrou…
