An equivalence theorem for algebraic and functorial QFT
Severin Bunk, James MacManus, Alexander Schenkel
The paper introduces a flexible notion of Lorentzian bordisms to define functorial quantum field theories and proves an equivalence between these theories and algebraic quantum fie…
Symmetries and Higher-Form Connections in Derived Differential Geometry
Severin Bunk, Lukas Müller, Joost Nuiten +1
We introduce a general definition of higher-form connections on principal -bundles in differential geometry. This is achieved by developing the formal differentiation and i…
The Cauchy problem for gradient generalized Ricci solitons on a bundle gerbe
Severin Bunk, Miguel Pino Carmona, C. S. Shahbazi
We prove well-posedness of the analytic Cauchy problem for gradient generalized Ricci solitons on an abelian bundle gerbe and solve the initial data equations on every compact Riem…
The local moduli space of the Einstein-Yang-Mills system
Severin Bunk, Vicente Muñoz, C. S. Shahbazi
We study the deformation theory of the Einstein-Yang-Mills system on a principal bundle with a compact structure group over a compact manifold. We first construct, as an applicatio…
Lorentzian bordisms in algebraic quantum field theory
Severin Bunk, James MacManus, Alexander Schenkel
It is shown that every algebraic quantum field theory has an underlying functorial field theory which is defined on a suitable globally hyperbolic Lorentzian bordism pseudo-categor…
