# General Boundary Quantum Field Theory in Anti de Sitter Spacetimes

@article{Dohse2016GeneralBQ, title={General Boundary Quantum Field Theory in Anti de Sitter Spacetimes}, author={Max Dohse}, journal={arXiv: Mathematical Physics}, year={2016} }

We mainly study real Klein-Gordon theory on Anti de Sitter spacetimes, and apply the General Boundary Formulation (GBF) of Quantum Theory in order to compute a radial S-matrix. We consider first the classical theory, giving a complete list of Klein-Gordon solutions and the actions of the isometries of AdS on them. We study two symplectic structures on spaces of such solutions, and show that they are invariant under all isometries' actions. We also calculate the flat limits of the involved…
