“…Let F be an unramified field extension of Q p . For a semistable representation of G F = Gal(F /F ), let D st,F denote the semistable Dieudonné functor over F (see [IS03,§2]); so if V is a semistable representation of G F , then D st,F (V ) is a filtered Frobenius monodromy module over F (see [IS03,§2]); the category of such objects is denoted MF φ,N F , and for an object D in this category we denote F • (D) its filtration. For an object D in MF φ,N F , define (4)…”
