Title: Embedding obstructions for non-toric rational surfaces from Newton-Okounkov bodies
Abstract: ECH capacities are invariants that have found many applications to embedding problems in symplectic geometry, most of which in the toric setting. I will discuss a new application of ECH to studying optimal embeddings for non-toric rational surfaces. The key convex geometric objects in our story are Newton-Okounkov bodies, which supply embeddings by work of Kaveh and also compute ECH capacities by recent joint work with Julian Chaidez.
