Title:
Surfaces and stable norms

Abstract:

Many fundamental geometric or topological problems can be couched in terms of finding a *simplest* representative of a given structure: a shortest path, a triangulation with fewest triangles, a least area surface. We discuss the theory of *stable commutator length*, ostensibly concerned with optimizing an algebraic quantity, and explain its relation to topology, geometry, and the homologically efficient construction of surfaces. There are many beautiful and unexpected phenomena. Some are understood; many more are not.
