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 $ρ$ 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 $ρ$ an explicit locally analytic $E$-representation $π\mathrm{min}(ρ)$ of $\mathrm{GSp}_4(\mathbb{Q}_p)$, which encodes enough information to determines $ρ$. Moreover, under certain settings, this construction follows the local-global compatibility.
