Abstract
We prove that a holonomic binomial Dmodule M A I β is regular if and only if certain associated primes of I determined by the parameter vector betain mathbbCd are homogeneous We further describe the slopes of M A I β along a coordinate subspace in terms of the known slopes of some related hypergeometric Dmodules that also depend on β When the parameter β is generic we also compute the dimension of the generic stalk of the irregularity of M A I β along a coordinate hyperplane and provide some remarks about the construction of its Gevrey solutionsPartially supported by MTM201019336 and FEDER and Junta de Andalucía under grants FQM5849 FQM333 MCFF supported by a grant from Iceland Liechtenstein and Norway through the EEA Financial Mechanism Supported and coordinated by Universidad Complutense de Madrid
