# Small distance behaviour in field theory and power counting

@article{Symanzik1970SmallDB, title={Small distance behaviour in field theory and power counting}, author={Kurt Symanzik}, journal={Communications in Mathematical Physics}, year={1970}, volume={18}, pages={227-246} }

For infinitesimal changes of vertex functions under infinitesimal variation of all renormalized parameters, linear combinations are found such that the net infinitesimal changes of all vertex functions are negligible relative to those functions themselves at large momenta in all orders of renormalized perturbation theory. The resulting linear first order partial differential equations for the asymptotic forms of the vertex functions are, in quantum electrodynamics, solved in terms of one… Expand
