Topology of algebraic maps
I will survey the study of topological properties of algebraic varieties through three crucial steps: the work of Lefschetz, Hodge theory, and the extension of these theories to singular varieties and to maps. At each step I will show how these results, when applied to toric varieties, yield a deeper insight on combinatorics of convex polytopes.
The talk will take place in the Salle des Professeurs at 16:30. Coffee, tea and biscuits will be served in the same room, from 16:00. The Salle des Professeurs is on the 9th floor of building NO, of the Campus de la Plaine. Maps of the campus and directions are available here.
