摘要	We construct the Frobenius structure on a rigid connection Be (sic) on G(m) for a split reductive group (sic) introduced by Frenkel-Gross. These data form a (sic)-valued overconvergent F-isocrystal Be-(sic)(dagger) on G(m), F-p, which is the p-adic companion of the Kloosterman (sic)-local system Kl((sic)) constructed by Heinloth-Ngo-Yun. By studying the structure of the underlying differential equation, we calculate themonodromy group of Be-(sic)(dagger) when (sic) is almost simple (which recovers the calculation of monodromy group of Kl((sic)) due to Katz and Heinloth-Ngo-Yun), and prove a conjecture of Heinloth-Ngo-Yun on the functoriality between different Kloosterman (sic)-local systems. We show that the Frobenius Newton polygons of Kl(sic) are generically ordinary for every (sic) and are everywhere ordinary on vertical bar G(m), F-p vertical bar when (sic) is classical or G(2).
