Computation of Vector-Valued Invariants for a Finite Complex Reflection Group

A. K. M. Selim Reza, Manabu Oura, Masashi Kosuda +1

We consider the complex reflection group \( \mathcal{G} \), identified as No. 8 in the Shephard-Todd classification. In this paper, we present computations of the vector-valued inv…

On p-divisibility of Fourier coefficients of Hermitian modular forms

Shoyu Nagaoka

We describe the -divisibility transposition for the Fourier coefficients of Hermitian modular forms. The results show that the same phenomenon as that for Siegel modular forms h…

Note on the Type II codes of length

Shoyu Nagaoka, Manabu Oura

We express the weight enumerators of self-dual and doubly even (Type II for short) codes of length with a specified basis. As a consequence, we present some congruence relatio…

On -divisibility of Fourier coefficients of Siegel modular forms

Shoyu Nagaoka

We describe the -divisibility transposition for the Fourier coefficients of Siegel modular forms. This provides a supplement to the result by Wilton for -divisibility satisfi…

A remark on -adic Siegel Eisenstein series

Hidenori Katsurada, Shoyu Nagaoka

A generalization of Serre's -adic Eisenstein series in the case of Siegel modular forms is studied and a coincidence between a -adic Siegel Eisenstein series and a genus thet…

Congruence relations satisfied by quaternionic modular forms

Shoyu Nagaoka

The theory of quaternionic modular forms has been studied for decades as an example of the modular forms of many variables. The purpose of this study is to provide some congruence…
