TITLE Chaos in 3D (higher spin) gravity
ABSTRACT

In this talk, I'll discuss SL(N) Chern-Simons higher spin gravity, and its boundary on-shell action. Then, I will discuss gravitationally dressed bi-local objects such as master field in the SL(N) Vasiliev equation and Wilson line. And, I will explain their soft higher spin mode expansion to derive soft mode eigenfunctions. I will also discuss the general form of soft mode eigenfunctions from W-Ward identity and null relation in W_N minimal model. Finally, from the on-shell action and the soft mode eigenfunction, I will evaluate the out-of-time-ordered correlators.
