متن کاملLarge - N quantum gauge theories in two dimensions
The partition function of a two-dimensional quantum gauge theory in the large-N limit is expressed as the functional integral over some scalar field. The large-N saddle point equation is presented and solved. The free energy is calculated as the function of the area and of the Euler characteristic. There is no non-trivial saddle point at genus g > 0. The existence of a non-trivial saddle point ...
متن کاملFrom Threebranes to Large N Gauge Theories *
This is a brief introductory review of the AdS/CFT correspondence and of the ideas that led to its formulation. Emphasis is placed on dualities between conformal large N gauge theories in 4 dimensions and string backgrounds of the formAdS5×X5. Attempts to generalize this correspondence to asymptotically free theories are also included.
متن کاملOn Large N Gauge Theories from Orientifolds
We consider four dimensional N = 1 supersymmetric gauge theories obtained via orientifolds of Type IIB on Abelian C/Γ orbifolds. We construct all such theories that have well defined world-sheet expansion. The number of such orientifolds is rather limited. We explain this fact in the context of recent developments in four dimensional Type IIB orientifolds. In particular, we elaborate these issu...
