Monodromy conjecture for log mixed objects

About 4 years old · traced to

Let kk be the base field, let P{\mathcal {P}} be the class of schemes considered in the source, and let X∈PX\in {\mathcal {P}}. The monodromy operator is

N:Hm(X)ℓ→Hm(X)ℓ(−1).N:H^m(X)_{\ell}\to H^m(X)_{\ell}(-1).

The associated objects Hm(X)♭H^m(X)^{\flat}, Hm(X)(−1)♭H^m(X)(-1)^{\flat}, Hm(X)♭∗H^m(X)^{\flat*}, and Hm(X)(−1)♭∗H^m(X)(-1)^{\flat*} are defined through the log and enlarged log categories. Monodromy conjecture. The operator NN comes from geometry rather than only from Galois theory: it is a morphism

Hm(X)♭→Hm(X)(−1)♭,H^m(X)^{\flat}\to H^m(X)(-1)^{\flat},

and hence a morphism

Hm(X)♭∗→Hm(X)(−1)♭∗.H^m(X)^{\flat*}\to H^m(X)(-1)^{\flat*}.

This is part of the broader comparison conjectures relating motivic morphisms to Hodge- and Tate-theoretic morphisms. The supplied text records it as an expectation and gives no resolution evidence.
