On Siegel--Eisenstein series of level $p$ and their $p$ -adic properties

Siegfried Boecherer, Keiichi Gunji, Toshiyuki Kikuta

We construct a Siegel--Eisenstein series of level $p$ with a quadratic character mod $p$ which is a $U (p)$ -eigenfunction with eigenvalue $1$ , and calculate its Fourier coefficients…

On $p$ -adic Siegel--Eisenstein series II: How to avoid the regularity condition for $p$

Siegfried Boecherer, Toshiyuki Kikuta

In a previous paper, the authors showed that two kinds of $p$ -adic Siegel--Eisenstein series of degree $n$ coincide with classical modular forms of weight $k$ for $I^_{0} (p)$ , under…
