Comparison conjecture for étale and logarithmic étale motives
Comparison conjecture for étale and logarithmic étale motives
Let be a field and let be the coefficient ring. Denote by and the effective logarithmic motive categories for the étale and logarithmic étale topologies, respectively.
Étale comparison conjecture. There is an equivalence of triangulated categories
The conjecture is motivated by comparison results for Hodge sheaves, while the failure of strict homotopy invariance for in the strict étale topology leaves the comparison of torsion cohomology unresolved.
