SUMMARY:Sung Gi Park\, Hodge symmetries of singular varieties
DESCRIPTION:    Speaker\n\n\nSung Gi Park\nPrinceton U. / IAS\n\n\n\n\n\n\nThe Hodge diamond of a smooth projective complex variety exhibits fundamental symmetries\, arising from Poincaré duality and the purity of Hodge structures. In the case of a singular projective variety\, the complexity of the singularities is closely related to the symmetries of the analogous Hodge-Du Bois diamond. For example\, the failure of the first nontrivial Poincaré duality is reflected in the defect of factoriality. Based on joint work with Mihnea Popa\, I will discuss how local and global conditions on singularities influence the topology of algebraic varieties.
