Abstract: We will discuss the extent to which symplectic manifolds have a natural notion of "size" or "complexity". A central role in this talk will be played by Liouville embeddings, which are a natural class of morphisms between open symplectic manifolds. We will introduce a family of symplectic invariants which give new obstructions for Liouville embeddings. As the main application, we will discuss the case of divisor complements in projective space, giving sharp obstructions in many cases. This is based on joint work in progress with Sheel Ganatra.
