QG group meeting: twistor-space quantization for the dS causal patch

This is the weekly QG group meeting.

Title: Twistor-space quantization for the dS causal patch.

I will describe the quantization of free massless fields in a causal patch of de Sitter space, using the twistor language of higher-spin gravity. This accomplishes two goals at the same time. On the one hand, is provides a translation into higher-spin-covariant language of my elliptic dS/CFT holographic dictionary. On the other hand, it is the first explicit quantization of massless fields in HS-covariant language in any context.
