Abstract

Let V\mathcal{V} be a mixed characteristic complete discrete valuation ring, kk its residual field, P\mathcal{P} a proper smooth formal scheme over V\mathcal{V}, PP its special fiber, TT a divisor of PP, U:=PTU:=P\setminus T, YY a smooth closed subscheme of UU. We prove that the category of overconvergent FF-isocrystals on YY is equivalent to the category of overcoherent FF-isocrystals on YY. More generally, we prove such an equivalence by gluing for any smooth variety YY over kk. Moreover, we check that overcoherent FF-complexes of arithmetic D\mathcal{D}-modules split in overconvergent FF-isocrystals.
