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…
An equivalence theorem for algebraic and functorial QFT
Severin Bunk, James MacManus, Alexander Schenkel
This paper develops a novel approach to functorial quantum field theories (FQFTs) in the context of Lorentzian geometry. The key challenge is that globally hyperbolic Lorentzian bo…
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…
-Bundles
Severin Bunk
Higher bundles are homotopy coherent generalisations of classical fibre bundles. They appear in numerous contexts in geometry, topology and physics. In particular, higher principal…
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…
