Reflection positivity in higher derivative scalar theories
Francesca Arici, Daniel Becker, Chris Ripken +2
Reflection positivity constitutes an integral prerequisite in the Osterwalder-Schrader reconstruction theorem which relates quantum field theories defined on Euclidean space to the…
An equivariant pullback structure of trimmable graph C*-algebras
Francesca Arici, Francesco D'Andrea, Piotr M. Hajac +1
We prove that the graph C*-algebra of a trimmable graph is -equivariantly isomorphic to a pullback C*-algebra of a subgraph C*-algebra and the C*-alge…
Quantum lattice gauge fields and groupoid C*-algebras
Francesca Arici, Ruben Stienstra, Walter D. van Suijlekom
We present an operator-algebraic approach to the quantization and reduction of lattice field theories. Our approach uses groupoid C*-algebras to describe the observables and exploi…
