Abstract
Let be a henselian DVR with field of fractions and residue field of characteristic . Let denote endowed with the canonical log structure. We show that the generic fiber functor between the category of dual representable log -divisible groups over and the category of -divisible groups with semistable reduction over is an equivalence. If is further complete with perfect residue field and of mixed characteristic, we show that is also equivalent to the category of semistable Galois -representations with Hodge-Tate weights in . Finally, we show that the above equivalences respect monodromies.
