Classical and Quantum Fields on Lorentzian Manifolds
Christian Baer, Nicolas Ginoux
We construct bosonic and fermionic locally covariant quantum field theories on curved backgrounds for large classes of fields. We investigate the quantum field and n-point function…

Boundary Value Problems for Elliptic Differential Operators of First Order
Christian Baer, Werner Ballmann
We study boundary value problems for linear elliptic differential operators of order one. The underlying manifold may be noncompact, but the boundary is assumed to be compact. We r…
