QG group meeting.
Speaker: Yasha Neiman.
Title: "Lightcone and unfolding - opposites yet the same".

The lightcone formalism for gauge theories sacrifices manifest Lorentz covariance so as to work with just the physical degrees of freedom. In contrast, Vasiliev's unfolded language describes the same degrees of freedom using every Lorentz representation at once. I will review both languages, and argue that they are secretly almost the same.
