Title: Cones of divisors, the cone theorem, and the cone conjecture
Abstract: The finite-dimensional vector space of divisors modulo numerical equivalence on a projective variety X contains several convex cones that tell you very useful and concrete geometric information about X. We will explore the structure of a few of these cones through theorems and examples, building up to some current work of myself and Joaquin Moraga.
