Families of symplectic Galois representations over small parabolic eigenvarieties for Siegel cuspforms of genus $2$

Muhammad Manji, Frederick E. Thøgersen, Ju-Feng Wu

We construct small parabolic eigenvarieties for holomorphic Siegel cuspforms of genus $2$ and study families of Galois representations attached to them in the spirit of Bellaïche--…

Overconvergent Eichler-Shimura morphisms for $GSp_{4}$

Hansheng Diao, Giovanni Rosso, Ju-Feng Wu

We construct explicit Eichler-Shimura morphisms for families of overconvergent Siegel modular forms of genus two. These can be viewed as $p$ -adic interpolations of the Eichler-Shim…

Eisenstein degeneration of Beilinson--Kato classes and circular units

Javier Polo, Óscar Rivero, Ju-Feng Wu

The aim of this note is to explore the Euler system of Beilinson--Kato elements in families passing through the critical $p$ -stabilization of an Eisenstein series attached to two D…

On Greenberg--Benois $L$ -invariants and Fontaine--Mazur $L$ -invariants

Ju-Feng Wu

We prove a comparison theorem between Greenberg--Benois $L$ -invariants and Fontaine--Mazur $L$ -invariants. Such a comparison theorem supplies an affirmative ans…
