Non-perturbative Field Theory
In this talk we review recent developments which enable us to use techniques of integrable twodimensional quantum field theories to solve exactly four dimensional N=4 gauge theory through the use of the AdS/CFT correspondence. By ‘solve’ we mean here to find all anomalous dimensions of all operators of the theory for any value of the gauge coupling. We illustrate the methods with the case of th...
متن کاملPerturbative Topological Field Theory
We give a review of the application of perturbative techniques to topologi-cal quantum eld theories, in particular three-dimensional Chern-Simons-Witten theory and its various generalizations. To this end we give an introduction to graph homology and homotopy algebras and the work of Vassiliev and Kontsevich on perturbative knot invariants.
متن کاملPerturbative diagrams in string field theory
A general algorithm is presented which gives a closed-form expression for an arbitrary perturbative diagram of cubic string field theory at any loop order. For any diagram, the resulting expression is given by an integral of a function of several infinite matrices, each built from a finite number of blocks containing the Neumann coefficients of Witten’s 3-string vertex. The closed-form expressi...
متن کاملString Field Theory and Perturbative Dynamics of Noncommutative Field Theory
The perturbative dynamics of noncommutative field theory (NCFT) is discussed from a point view of string field theory. As in the commutative case it is inevitable to introduce a closed string, which may be described as a bound state of two open strings. We point out that the closed string, interacting nontrivially with the open string, plays an essential role in the ultraviolet region. The cont...
متن کاملAre Pions Perturbative in Effective Field Theory?
It is shown that pions can be included perturbatively into effective field theory only for the external momenta, well below the pion mass. But for such low energies it is not necessary to include pions explicitly. 03.65.Nk, 11.10.Gh, 12.39.Fe, 13.75.Cs. Typeset using REVTEX
