p-adic Hodge parameters in the crystalline representations of GSp4

Abstract

This article gives a generalization of the work of Y.Ding in the context of ${\mathrm{GSp}}_4({\mathbb{Q}}_p)$, where $p$ is an odd prime number. Let $\rho$ be a 4-dimensional generic non-critical crystalline representations of the absolute Galois group of ${\mathbb{Q}}_p$ of regular Hodge-Tate weights which is valued in ${\mathrm{GSp}}_4(E)$, where $E$ is a finite extension of ${\mathbb{Q}}_p$, we associate to $\rho$ an explicit locally analytic $E$-representation ${\pi }_{\min }(\rho )$ of ${\mathrm{GSp}}_4({\mathbb{Q}}_p)$, which encodes enough information to determines $\rho$. Moreover, under certain settings, this construction follows the local-global compatibility.
