Wall-crossing and $p$ -adic Artin formalism for $GSp_{4} \times GL_{2} \times GL_{2}$

Kâzım Büyükboduk, Óscar Rivero, Ryotaro Sakamoto

The goal of this article is to develop a $p$ -adic Artin formalism in the context of $p$ -adic families of automorphic forms on $GSp_{4} \times GL_{2} \times GL_{2}$ . Our…

Classifications of Hecke Fields and Galois Images of Weight One Exotic Newforms

Ryotaro Sakamoto, Sho Yoshikawa

We determine the Hecke fields associated with weight one newforms of $A_{4}$ -, $S_{4}$ -, and $A_{5}$ -type, expressed in terms of the order of its nebentypus. Furthermore, for each type,…

On the Artin formalism for triple product $p$ -adic $L$ -functions

Kâzım Büyükboduk, Ryotaro Sakamoto

Our main objective in the present article is to study the factorisation problem for triple-product $p$ -adic $L$ -functions, particularly in the scenarios when the defining propertie…
