In this first lecture, we shall begin by constructing a CW-structure for the complex Grassmannian. We will then begin our exploitation of this CW-structure with the goal of answering questions in enumerative geometry. These questions include “How many lines lie on the intersection of two quadric hypersurfaces in P^4?” and “Given four smooth curves in P^3, how many lines will intersect all four curves?”
