States and amplitudes for finite regions in a two-dimensional Euclidean quantum field theory
Daniele Colosi, Robert Oeckl
We quantize the Helmholtz equation (plus perturbative interactions) in two dimensions to illustrate a manifestly local description of quantum field theory. Using the general bounda…

Hopf algebras and the combinatorics of connected graphs in quantum field theory
Angela Mestre, Robert Oeckl
In this talk, we are concerned with the formulation and understanding of the combinatorics of time-ordered n-point functions in terms of the Hopf algebra of field operators. Mathem…

Spatially asymptotic S-matrix from general boundary formulation
Daniele Colosi, Robert Oeckl
We construct a new type of S-matrix in quantum field theory using the general boundary formulation. In contrast to the usual S-matrix the space of free asymptotic states is located…
