##
Wilson loops in N=4 Supersymmetric Yang-Mills Theory

### Abstract

Wilson loops in N=4, D=4 supersymmetric Yang-Mills theory admit
the string representation in the large-N and large coupling limit via the
AdS/CFT correspondence. I will discuss perturbative computations of Wilson
loops in N=4 SYM. Though perturbative computations are pertinent to the
weak coupling regime, I will show that the sum of an infinite class of
ladder diagrams, when extrapolated to the strong coupling, produces
results characteristic of the AdS/CFT predictions. For circular loops,
this sum of is conjectured to give an exact result.
