Extended Body Propagators

Rory O'Dwyer

Three seemingly distinct extended-body propagators devised by Ansoldi et al., Erbin et al., and Stanford et al.\ respectively arise in completely different settings, though each ca…

A Geometric Picture of Perturbative QFT

Rory O'Dwyer

In previous work, a lattice scalar propagator was rigorously defined in $d = 1$ flat space and shown to equal the known Klein-Gordon propagator of QFT. This work generalizes this lat…

Relativistic Propagators on Lattices

Rory O'Dwyer

I define the lattice propagator on a very general collection of graphs, namely graphs locally isomorphic to $Z^{d} \times Z$ . I then define polygonal approximation…
