Rev. Mod. Phys. 59, 235–261 (1987)Some aspects of large-N theories
This is a pedagogical review of some aspects of quantum field theories in the limit in which the number of internal degrees of freedom is large. The focus is on large-N QCD. The authors briefly discuss several well-known approaches to a solution of the N=∞ limit: loop equations, classical actions, and master fields. Eguchi-Kawai models are discussed in detail, and some recently obtained numerical results are reviewed. © 1987 The American Physical Society URL:
