A 0-dimensional counter-example to rooting?
Giancarlo Rossi, Massimo Testa
TL;DR
This paper presents a specific 0-dimensional field theory example demonstrating that the rooting procedure, often used in quantum field theory, can fail in certain cases.
Contribution
It introduces a novel 0-dimensional counter-example showing the limitations of the rooting method in field theories.
Findings
Rooting can fail in 0-dimensional models.
Counter-example challenges assumptions about rooting.
Highlights need for caution in applying rooting.
Abstract
We provide an example of a 0-dimensional field theory where rooting does not work.
