Boundary terms in supergravity and supersymmetry

摘要

We begin with the simplest possible introduction to supergravity, and then discuss its spin-3/2 stress tensor. Next, we discuss boundary conditions on fields and boundary actions for N = 1 supergravity. Finally, we discuss new boundary contributions to the mass and central charge of monopoles in N = 4 super Yang-Mills theory. All models are in (3+1) dimensions.
