From d=2 Virasoro blocks to something analogous in d=4
Abstract: Motivated by generalising the Virasoro vacuum blocks in d=2 CFTs to higher dimensions, I will discuss recent progress in understanding the multi-stress tensor sector of the heavy-light four-point scalar correlator in holographic CFTs in d=4. By focusing on the correlator in the near-lightcone regime, I will point out that, at certain values of the conformal dimension of the light probe operators, the d=4 correlator obeys a system of linear differential equations that share striking similarity with the d=2 BPZ equations at large central charge.

Holographic Complexity Beyond Proposals and Beyond Anti-de Sitter
Abstract: I will discuss recent progress in understanding holography of hardness of state preparation ab initio and show how it can work in a new to it setting of de Sitter universes. Based on 2203.08842, 2212.00043 and 2305.11280.
