Abstract
Motivated by a question of Hansen and Li, we show that a smooth and proper rigid analytic space with projective reduction satisfies Hodge symmetry in the following situations: (1) the base non-archimedean field is of residue characteristic zero, (2) is -adic and has good ordinary reduction, (3) is -adic and has "combinatorial reduction."' We also reprove a version of their result, Hodge symmetry for , without the use of moduli spaces of semistable sheaves. All of this relies on cases of Kato's log hard Lefschetz conjecture, which we prove for and for log schemes of "combinatorial type."
