The Mirror Clemens-Schmid Sequence

本文提出联系光滑簇与补开集上同调的四项长正合序列，证明其兼容反常 Leray 滤过和混合 Hodge 结构，并通过 K3、Calabi–Yau 及五次三维簇退化验证其为 Clemens–Schmid 序列的镜像。

Tropical Clemens-Schmid sequence and existence of tropical cycles with a given cohomology class

This is a sequel to our work in tropical Hodge theory. Our aim here is to prove a tropical analogue of the Clemens-Schmid exact sequence in asymptotic Hodge theory. As an application of this result, we prove the tropical Hodge conjecture for smooth projective tropical varieties which are rationally triangulable. This provides a partial answer to a question of Kontsevich who suggested the validity of the tropical Hodge conjecture could be used as a test for the validity of the Hodge conjecture.

Hodge theory of degenerations, (I): Consequences of the decomposition theorem

We use the Decomposition Theorem to derive several generalizations of the Clemens-Schmid sequence, relating asymptotic Hodge theory of a degeneration to the mixed Hodge theory of its singular fiber(s).

Monodromy Criterion for the Good Reduction of K3 Surfaces

We give a criterion for the good reduction of semistable $K3$ surfaces over $p$-adic fields using purely $p$-adic methods. We use neither $p$-adic Hodge theory nor transcendental methods as in the analogous proofs of criteria for good reduction of curves or $K3$ surfaces. We achieve our goal by realizing the special fiber $X_s$ of a semistable model $X$ of a $K3$ surface over the $p$-adic field $K$, $X_K$ as a special fiber of a log-family in characteristic $p$ and use an arithmetic version of the Clemens-Schimd exact sequence in order to obtain a Kulikov-Persson-Pinkham classification theorem…
