Surprising consequence of a positive cosmological constant
Speaker(s): Beatrice Bonga
Abstract:

The study of isolated systems has been vastly successful in the context of vanishing cosmological constant, $Lambda = 0$. However, there is no physically useful notion of asymptotics for the universe we inhabit with $Lambda > 0$. The full non-linear framework is still under development, but some interesting results at the linearized level have been obtained. I will focus on the conceptual subtleties that arise at the linearized level and discuss the quadrupole formula for gravitational radiation.
