IR dynamics of QFT in dS -- Victor Gorbenko (Stanford)
I present a formalism designed to treat Quantum Field Theories in de Sitter space. This formalism is manifestly IR safe and thus resolves the issue of IR divergences to all orders in perturbation theory. I will use the example of \lambda \phi^4 theory, since the IR issue was most prominent in the theories of light self-interacting scalar fields.
