# Generalized Tomonaga-Schwinger equation from the Hadamard formula

@article{Doplicher2004GeneralizedTE, title={Generalized Tomonaga-Schwinger equation from the Hadamard formula}, author={Luisa Doplicher}, journal={Physical Review D}, year={2004}, volume={70}, pages={064037} }

A generalized Tomonaga-Schwinger equation, holding on the entire boundary of a finite spacetime region, has recently been considered as a tool for studying particle scattering amplitudes in background-independent quantum field theory. The equation has been derived using lattice techniques under assumptions on the existence of the continuum limit. Here I show that in the context of continuous Euclidean field theory the equation can be directly derived from the functional integral formalism…
