The p-adic monodromy-weight conjecture for projective log smooth schemes

Let S\overset{\circ}{S} be a pp-adic formal scheme and let XS\overset{\circ}{X}\to\overset{\circ}{S} be projective. For a log smooth scheme Y/SY/S, let

N ⁣:RuY/S(OY/S)RuY/S(OY/S)(1)N\colon Ru_{Y/S*}(\mathcal O_{Y/S})\longrightarrow Ru_{Y/S*}(\mathcal O_{Y/S})(-1)

be the monodromy operator, and let PP denote the weight filtration on RqfX/S(OX/S)R^qf_{X/S*}(\mathcal O_{X/S}). pp-adic monodromy-weight conjecture. For every nonnegative integer qq and every eNe\in\mathbb N, the morphism

Ne ⁣:grq+ePRqfX/S(OX/S)grqePRqfX/S(OX/S)(e)N^e\colon \operatorname{gr}^P_{q+e}R^qf_{X/S*}(\mathcal O_{X/S})\longrightarrow \operatorname{gr}^P_{q-e}R^qf_{X/S*}(\mathcal O_{X/S})(-e)

is an isomorphism modulo torsion. This is presented as a pp-adic analogue and generalization of earlier monodromy-weight conjectures; the source gives no resolution status.
