On the coordinate (in)dependence of the formal path integral
Theo Johnson-Freyd
When path integrals are discussed in quantum field theory, it is almost always assumed that the fields take values in a vector bundle. When the fields are instead valued in a possi…

Feynman-diagrammatic description of the asymptotics of the time evolution operator in quantum mechanics
Theo Johnson-Freyd
We describe the "Feynman diagram" approach to nonrelativistic quantum mechanics on R^n, with magnetic and potential terms. In particular, for each classical path γconnecting points…
