Chern-Simons Gauge Theory as a String Theory

by Edward Witten , 2003
"... Certain two dimensional topological field theories can be interpreted as string theory backgrounds in which the usual decoupling of ghosts and matter does not hold. Like ordinary string models, these can sometimes be given space-time interpretations. For instance, three-dimensional Chern-Simons gaug ..."

-Simons gauge theory can arise as a string theory. The world-sheet model in this case involves a topological sigma model. Instanton contributions to the sigma model give rise to Wilson line insertions in the space-time Chern-Simons theory. A certain holomorphic analog of Chern-Simons theory can also arise as a

Anti-de Sitter Space, Thermal Phase Transition, and Confinement in Gauge Theories

by Edward Witten - Adv. Theor. Math. Phys , 1998
"... The correspondence between supergravity (and string theory) on AdS space and boundary conformal field theory relates the thermodynamics of N = 4 super Yang-Mills theory in four dimensions to the thermodynamics of Schwarzschild black holes in Anti-de Sitter space. In this description, quantum phenome ..."

. By similar methods, one can also make a speculative proposal for the description of large N gauge theories in four dimensions without supersymmetry. March

On the gauge theory/geometry correspondence

by Rajesh Gopakumar, Cumrun Vafa - Adv. Theor. Math. Phys , 1999
"... The ’t Hooft expansion of SU(N) Chern-Simons theory on S3 is proposed to be exactly dual to the topological closed string theory on the S2 blow up of the conifold geometry. The B-field on the S2 has magnitude Ngs = λ, the ’t Hooft coupling. We are able to make a number of checks, such as finding exa ..."

, in terms of holes in the closed string worldsheet, arises automatically from the coexistence of two phases in the underlying U(1) gauge theory. This approach holds promise for a derivation of the AdS/CFT correspondence.

Gauge Theories

"... We calculate conformal anomalies in noncommutative gauge theories by using path integral method (Fujikawa’s method). As well as the axial anomalies and chiral gauge anomalies, the conformal anomalies take the form of the straightforward Moyal deformation in the corresponding conformal anomalies in o ..."

Gauge Theory on Noncommutative Spaces

"... We introduce a formulation of gauge theory on noncommutative spaces based on the concept of covariant coordinates. Some important examples are discussed in detail. A Seiberg-Witten map is established We introduce a natural method to formulate a gauge theory on more or less arbitrary noncommutative s ..."

Macroscopic strings as heavy quarks in large N gauge theory and Anti-de Sitter supergravity

Gauge Theories ∗

by Frank J. Petriello , 2001
"... This paper investigates the non-commutative version of the Abelian Higgs model at the one loop level. We find that the BRST invariance of the theory is maintained at this order in perturbation theory, rendering the theory one-loop renormalizable. Upon removing the gauge field from the theory we also ..."
