Invariant quantization in warped spacetimes
Philippe Droz-Vincent
We argue that quantum theory in curved spacetime should be invariant under the continuous spacetime symmetries thaat are connected with the identity. For typical warped-product spa…
Mode solutions of the Klein-Gordon equation in warped spacetimes
Philippe Droz-Vincent
In order to reduce the Klein-Gordon equation (with minimal coupling), we introduce a generalization of the so-called "mode solutions" that are well-known in the special case of a R…
Isometric invariance of the positive-frequency kernel in generalized FRW-like spacetimes
Ph. Droz-Vincent
Klein-Gordon equation with minimal coupling in FRW-like spacetimes with compact but not necessarily isotropic neither homogeneous space sections. Beside exceptional cases, the kern…
Invariance of Positive-Frequency Kernels in Generalized FRW Spacetimes
Ph. Droz-Vincent
We consider the Klein-Gordon equation in FRW-like spacetimes, with compact space sections (not necessarily isotropic neither homogeneous). The bi-scalar kernel allowing to select t…
