Euler Systems for $GSp_{4} \times GL_{2}$

Chi-Yun Hsu, Zhaorong Jin, Ryotaro Sakamoto

For a non-endoscopic cohomological cuspidal automorphic representation of $GSp_{4} \times GL_{2}$ , assumed to be $p$ -ordinary, we construct an Euler system for the Ga…

Fourier coefficients of the overconvergent generalized eigenform associated to a CM form

Chi-Yun Hsu

Let f be a modular form with complex multiplication. If f has critical slope, then Coleman's classicality theorem implies that there is a p-adic overconvergent generalized Hecke ei…

Ramification of Hilbert eigenvarieties at classical points

Chi-Yun Hsu

Andreatta-Iovita-Pilloni constructed eigenvarieties for cuspidal Hilbert modular forms. The eigenvariety has a natural map to the weight space, called the weight map. At a classica…

Shimura varieties at level $Γ_{1} (p^{\infty})$ and Galois representations

Ana Caraiani, Daniel R. Gulotta, Chi-Yun Hsu +4

We show that the compactly supported cohomology of certain $U (n, n)$ or $Sp (2 n)$ -Shimura varieties with $Γ_{1} (p^{\infty})$ -level vanishes above the middle degree. The…
