The Kähler identity for bigraded Hodge-Lefschetz modules and its application in non-archimedean Arakelov geometry. (English) Zbl 0954.14017

Summary: We prove a Kähler identity for bigraded Hodge-Lefschetz modules and discuss its applications in non-archimedean Arakelov geometry. We consider, in particular, the bigraded Hodge-Lefschetz modules associated by Bloch, Gillet, and Soulé with a principal divisor with strict normal crossings on a scheme. The Kähler identity is used to prove a refined analogue of the \(dd^c\)-lemma for differential forms for these bigraded Hodge-Lefschetz modules. We apply this refined non-archimedean \(dd^c\)-lemma to investigate the arithmetic intersection pairing between cycles supported on the special fibers of semi-stable models of curves and abelian varieties.
