TITLE: Hodge structures and the topology of algebraic varieties

ABSTRACT: We review the major progress made since the 50’s in our understanding of the topology of complex algebraic varieties. Most of the results  we will discuss  rely on Hodge theory, which  has some analytic aspects giving the Hodge and Lefschetz decompositions, and the Hodge-Riemann relations. We will see that a crucial ingredient, the existence of a polarization,  is missing in the general Kaehler context.
We will also discuss some results and problems related to algebraic cycles and motives.

Talk chair: Joe Harris

Written articles will accompany each lecture in this series and be available as part of the publication “History and Literature of Mathematical Science.”
