Pretalk: Introduction to intersection theory

Research talk: Towards an intersection theory with quadratic forms

Abstract: Intersection theory via algebraic cycles provides important tools in enumerative geometry. Recent advances in motivic homotopy theory have led to an enriched enumerative geometry with quadratic forms. I will discuss a corresponding intersection theory with applications in topology, geometry and arithmetics. Based on joint work with F. Déglise, N. Feld and A. Khan.
