A test of the Maldacena conjecture Gordon W. Semenoff University of British Columbia The AdS/CFT correspondence postulates an exact correspondence between a host of gravitational systems and their gauge theory duals. This seminar will review results on testing this postulate by comparing the computation of quantities using the two schemes. In particular, a certain Wilson loop operator can be computed to all orders in perturbation theory in N=4 super-Yang Mills theory. Comparison of its strong coupling behavior with computations using the supergravity dual provide a non-trivial test of the AdS/CFT correspondence. Some other aspects of computations of Wilson loops are reviewed.
