Combinatorial Dyson-Schwinger equations in noncommutative field theory

چکیده
We introduce here the Hopf algebra structure describing the noncommutative renormalization of a recently introduced translation-invariant model on Moyal space. We define Hochschild one-cocyles B γ + which allows us to write down the combinatorial DysonSchwinger equations for noncommutative quantum field theory. Oneand two-loops examples are explicitly worked out.

Integrability of Schwinger-Dyson Equations in 2D Quantum Gravity and c < 1 Non-critical String Field Theory
We investigate the integrability of the Schwinger-Dyson equations in c = 1 − 6 m(m+1) string field theory which were proposed by Ikehara et al as the continuum limit of the Schwinger-Dyson equations of the matrix chain model. We show the continuum Schwinger-Dyson equations generate a closed algebra. This algebra contains Virasoro algebra but does not coincide with W∞ algebra. We include in the ...
متن کاملStructures in Feynman Graphs - Hopf Algebras and Symmetries
We review the combinatorial structure of perturbative quantum field theory with emphasis given to the decomposition of graphs into primitive ones. The consequences in terms of unique factorization of Dyson– Schwinger equations into Euler products are discussed.
متن کاملComplex Langevin Equations and Schwinger-Dyson Equations
Stationary distributions of complex Langevin equations are shown to be the complexified path integral solutions of the Schwinger-Dyson equations of the associated quantum field theory. Specific examples in zero dimensions and on a lattice are given. Relevance to the study of quantum field theory phase space is discussed.
متن کاملString field theory in the temporal gauge.
We construct the string eld Hamiltonian for c = 1 6 m(m+1) string theory in the temporal gauge. In order to do so, we rst examine the Schwinger-Dyson equations of the matrix chain models and propose the continuum version of them. Results of boundary conformal eld theory are useful in making a connection between the discrete and continuum pictures. The W constraints are derived from the continuu...
متن کاملTadpole Summation by Dyson-Schwinger Equations
In quantum field theory with three-point and four-point couplings the Feynman diagrams of perturbation theory contain momentum independent subdiagrams, the “tadpoles” and “snails”. With the help of Dyson-Schwinger equations we show how these can be summed up completely by a suitable modification of the mass and coupling parameters. This reduces the number of diagrams significantly. The method i...
