The relative p-adic monodromy-weight conjecture for a proper SNCL scheme with a relative SNCD

Let SS be a pp-adic scheme, let X/S0X/S_0 be a proper SNCL scheme with relative SNCD DD, and let f ⁣:XSf\colon X\to S be the structural morphism. Let PP and PDP^D be the weight filtrations on Rqf(X,D)/S(O(X,D)/S)R^qf_{(X,D)/S*}(\mathcal O_{(X,D)/S}), and let

N ⁣:Rqf(X,D)/S(O(X,D)/S)Rqf(X,D)/S(O(X,D)/S)(1)N\colon R^qf_{(X,D)/S*}(\mathcal O_{(X,D)/S})\longrightarrow R^qf_{(X,D)/S*}(\mathcal O_{(X,D)/S})(-1)

be the monodromy operator. Relative p-adic monodromy conjecture. If X\overset{\circ}{X} is projective over S\overset{\circ}{S}, then the relative monodromy filtration MM with respect to PDP^D exists and equals PP. Equivalently, for q,e,kNq,e,k\in\mathbb N, the induced morphism

Ne ⁣:grq+k+ePgrkPDRqf(X,D)/S(O(X,D)/S)grq+kePgrkPDRqf(X,D)/S(O(X,D)/S)(e)N^e\colon \operatorname{gr}^P_{q+k+e}\operatorname{gr}^{P^D}_k R^qf_{(X,D)/S*}(\mathcal O_{(X,D)/S})\longrightarrow \operatorname{gr}^P_{q+k-e}\operatorname{gr}^{P^D}_k R^qf_{(X,D)/S*}(\mathcal O_{(X,D)/S})(-e)

is an isomorphism modulo torsion. The conjecture extends the monodromy-weight statement to the bifiltered complex associated with a relative SNCD; the source gives no resolution status.
