Abstract

This article gives a generalization of the work of Y.Ding in the context of GSp4(Qp)\mathrm{GSp}_4(\mathbb{Q}_p), where pp is an odd prime number. Let ρ\rho be a 4-dimensional generic non-critical crystalline representations of the absolute Galois group of Qp\mathbb{Q}_p of regular Hodge-Tate weights which is valued in GSp4(E)\mathrm{GSp}_4(E), where EE is a finite extension of Qp\mathbb{Q}_p, we associate to ρ\rho an explicit locally analytic EE-representation πmin(ρ)\pi_\mathrm{min}(\rho) of GSp4(Qp)\mathrm{GSp}_4(\mathbb{Q}_p), which encodes enough information to determines ρ\rho. Moreover, under certain settings, this construction follows the local-global compatibility.
