Finiteness for self-dual classes in integral variations of Hodge structureArticle

Authors: Benjamin Bakker ; Thomas W. Grimm ; Christian Schnell ; Jacob Tsimerman

We generalize the finiteness theorem for the locus of Hodge classes with fixed self-intersection number, due to Cattani, Deligne, and Kaplan, from Hodge classes to self-dual classes. The proof uses the definability of period mappings in the o-minimal structure $\mathbb{R}_{\mathrm{an},\exp}$.
