TY - JOUR A1 - Shojaei-Fard, Ali T1 - A GEOMETRIC PERSPECTIVE ON COUNTERTERMS RELATED TO DYSON-SCHWINGER EQUATIONS T2 - INTERNATIONAL JOURNAL OF MODERN PHYSICS A N2 - We study Dyson-Schwinger equations (DSEs) in terms of some groups of diffeographisms to provide a new geometric formulation for their corresponding counterterms on the basis of systems of ordinary differential equations.
