GT seminar: Singular Lagrangian Fibrations and Applications to Symplectic Embeddings

Abstract: We construct explicit singular Lagrangian fibrations on disk cotangent bundles and show how simple manipulations of their base diagrams produce toric domains that encode sharp symplectic embeddings. The method recovers and streamlines known computations, offering a geometric, picture-driven route to embedding results. (Joint with R. Vianna and A. Vicente).

This is a talk in our Geometry and Topology Seminar Series.
