Construction of Hadamard states by characteristic Cauchy problem
Christian Gérard, Michał Wrochna
We construct Hadamard states for Klein-Gordon fields in a spacetime equal to the interior of the future lightcone from a base point in a globally hyperbolic spaceti…

Classical phase space and Hadamard states in the BRST formalism for gauge field theories on curved spacetime
Michał Wrochna, Jochen Zahn
We investigate linearized gauge theories on globally hyperbolic spacetimes in the BRST formalism. A consistent definition of the classical phase space and of its Cauchy surface ana…

Hadamard states for the linearized Yang-Mills equation on curved spacetime
Christian Gérard, Michal Wrochna
We construct Hadamard states for the Yang-Mills equation linearized around a smooth, space-compact background solution. We assume the spacetime is globally hyperbolic and its Cauch…
