Feynman Propagators on Static Spacetimes
Jan Dereziński, Daniel Siemssen
We consider the Klein-Gordon equation on a static spacetime and minimally coupled to a static electromagnetic potential. We show that it is essentially self-adjoint on $C_{\mathrm{…

Bosonic quadratic Hamiltonians
Jan Dereziński
We discuss self-adjoint operators given formally by expressions quadratic in bosonic creation and annihilation operators. We give conditions when they can be defined as self-adjoin…
