Fontaine describes in §2 of this old survey work by Wintenberger and wonders (on p. 97) that the structures found by Wintenberger are a "complete mystery" and no-one knows a "reasonable geometric interpretation". Is that still a mystery?

    $\begingroup$ Perhaps it would help if you mentioned that the structures in question are canonical $\mathbb{Z}_p$-integral structures on the de Rham cohomology of a smooth proper scheme over $W$, the ring of Witt vectors over a perfect field of characteristic $p$. $\endgroup$

    $\begingroup$ Thanks Scott, but what should be the mystery? Did you read Winterberger's articles? (I didn't) $\endgroup$
