DESCRIPTION:Attempts to formulate supersymmetric field theorie
s on discrete spacetime lattices have a long histo
ry. However\, until recently most of these efforts
have failed. In this talk I will review some of t
he new ideas that have finally allowed a solution
to this problem for certain supersymmetric theorie
s. I will focus my attention\, in particular\, on
N=4 super Yang-Mills which forms one of the pillar
s of the AdSCFT correspondence connecting gravitat
ional theories in anti-deSitter space to gauge the
ories living on the boundary. It is also integral
to the scattering amplitudes program and is under
intensive study using conformal bootstrap techniqu
es. I will review the theoretical construction of
the model and describe what is known analytically
about the lattice theory. Following on from this I
will present preliminary results stemming from th
e first large scale lattice study of N=4 Yang-Mill
s.
