In recent years, remarkable algebraic structures have been discovered in the quest to perform exact non-perturbative computations in supersymmetric quantum field theory, with deep connections to geometry and representation theory. I will try to explain how some these algebraic structures arise in simple examples, including Landau levels on a sphere, monopoles creating and destroying vortices, and interfaces colliding with boundaries.
