The zariskian p-adic bifiltered El Zein-Steenbrink-Zucker complex of a proper SNCL scheme with a relative SNCD

Yukiyoshi Nakkajima

We formulate the log -adic relative monodromy-weight conjecture and prove it in certain cases.

The -adic bifiltered El Zein-Steenbrink-Zucker complex of a proper SNCL scheme with a relative SNCD

Yukiyoshi Nakkajima

For a family of log points with constant log structure and for a proper SNCL scheme with an SNCD over the family, we construct a fundamental l-adic bifiltered complex as a geometri…

Derived categories of bifiltered complexes

Yukiyoshi Nakkajima

We construct a fundamental theory of the derived category of non-finite bi-filtered complexes.

Theory of weights for log convergent cohomologies II: the case of a proper SNCL scheme in characteristic

Yukiyoshi Nakkajima

For a flat -adic formal family of log points over a complete discrete valuation ring with perfect residue field of mixed characteristics and for a simple normal cros…

Steenbrink isomorphism and crystals on tubular neighbourhoods

Yukiyoshi Nakkajima

For a locally nilpotent integrable connection on a proper (strict) semistable family over a small polydisc with a relative horizontal simple normal crossing divisor, we construct a…
