“…By a theorem of Chiarellotto and Le Stum ( [8], Proposition 2.4.1), this implies that the comparison morphism y in De®nition 1.8 is an isomorphism. The only thing preventing the object Log n from splitting is the connection.…”

“…The upshot of the previous section is that we now have an affine group scheme π rig 1 (X/S, p) over the Tannakian category F-Isoc † (S/K) whose fibre (ignoring Frobenius structures) over any closed point s is the usual rigid fundamental group π rig 1 (X s , p s ) as defined by Chiarellotto and le Stum in [CLS99a]. In Chapter II of [Chi98], Chiarellotto defines a Frobenius isomorphism F * : π rig 1 (X s , p s ) ∼ → π rig 1 (X s , p s ), by using the fact that Frobenius pullback induces an automorphism of the category N Isoc † (X s /K).…”

“…This includes work of Chiarellotto and Le Stum [5], Kim and Hain [19,20], Shiho [35,36], and Vologodsky [42] among others. Thus the main new contribution of this paper is to extend some of the above work to a theory with non-unipotent coefficients, though we also obtain some new results about rational homotopy theory.…”
