dc.description.abstract	We determine the irregular Hodge filtration, as introduced by Sabbah, for the purely irregular hypergeometric D-modules. We obtain, in particular, a formula for the irregular Hodge numbers of these systems. We use the reduction of hypergeometric systems from GKZ-systems as well as comparison results to Gauss–Manin systems of Laurent polynomials via Fourier–Laplace and Radon transformations.	es
