Contribution
It provides the first detailed discussion of boundary terms in supergravity and reveals new boundary contributions to monopole properties in N=4 super Yang-Mills.
Findings
New results on spin 3/2 stress tensor in supergravity
Boundary conditions and actions for N=1 supergravity
Boundary contributions to monopole mass and central charge
Abstract
We begin with the simplest possible introduction to supergravity. Then we discuss its spin 3/2 stress tensor; these results are new. 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.
