Lefschetz theorems, Q-factoriality, and Hodge symmetry for singular varieties

Sung Gi Park, Mihnea Popa

Published 2024-10-21Version 1

We prove a number of new results concerning the topology and Hodge theory of singular varieties. A common theme is that concrete conditions on the complexity of the singularities are closely related to the symmetries of the Hodge-Du Bois diamond.
