Combinatorics of renormalization as matrix calculus
Ebrahimi Fard, Kurusch; Gracia Bondía, José M.; Guo, Li; Várilly Boyle, Joseph C. (2006)We give a simple presentation of the combinatorics of renormalization in perturbative quantum field theory in terms of triangular matrices. The prescription, that may be of calculational value, is derived from first ...
