On -adic quaternionic Eisenstein series
Toshiyuki Kikuta, Shoyu Nagaoka
We show that certain -adic Eisenstein series for quaternionic modular groups of degree 2 become "real" modular forms of level in almost all cases. To prove this, we introduc…
Bounds for Siegel Modular Forms of genus 2 modulo
Dohoon Choi, YoungJu Choie, Toshiyuki Kikuta
Sturm obtained the bounds for the number of the first Fourier coefficients of elliptic modular form to determine vanishing of modulo a prime . In this paper, we study an…
Sturm type theorem for Siegel modular forms of degree 2
Toshiyuki Kikuta
We attempt to generalize a congruence property of elliptic modular forms proved by Sturm to that of Haupttypus of Siegel modular forms of degree 2 with level. Namely, we give an ex…
On -adic Siegel modular forms of non-real Nebentypus of degree 2
Toshiyuki Kikuta
We show that all Siegel modular forms of non-real Nebentypus for are -adic Siegel modular forms by using a Maass lift.
