Exploring the asymptotics of scalar fields near spatial infinity

In this talk, I'll explore how tools from conformal geometry help us study global features of spacetime using local differential geometry techniques. Specifically, I'll focus on a particular conformal representation of Minkowski spacetime, which provides insights into the behaviour of massless fields near spatial infinity. We'll take a look at how this representation can be applied to analyze the asymptotics of the wave equation and use that to calculate asymptotic conserved quantities for the field.
