Abstract: Faces of the stable commutator length norm ball

It often happens that a solution of an extremal problem in geometry has more regularity and nicer features than one has an a priori right to expect. I will show how a simple topological problem—when does an immersed curve on a surface bound an immersed subsurface?—is unexpectedly related to linear programming in nonseparable Banach spaces, and gives rise to geometric and dynamical rigidity and discreteness of symplectic representations.
