In this article we consider gauge theories with a U(N) × U(N) gauge group. We provide, for the first time, a complete set of operators built from scalar fields that are in the bi fundamental of the two groups. Our operators diagonalize the two point function of the free field theory at all orders in 1/N . We then use this basis to investigate non-planar(More)
E-business systems involve a large number of nonfunctional requirements, such as performance, distribution, reliability, security, scalability, auditing, fail over, fault tolerance, resuming, clustering/load balancing, portability, accessibility, usability, etc. Such requirements increase the complexity of the system, and depending on programmers'(More)
