Abstract
We use results on Virasoro conformal blocks to study chaotic dynamics in
CFT\$\_2\$ at large central charge c. The Lyapunov exponent \$łambda\_L\$, which is
a diagnostic for the early onset of chaos, receives \$1/c\$ corrections that may
be interpreted as \$łambda\_L = 2 \pi\beta łeft( 1 + 12c
\right)\$. However, out of time order correlators receive other equally
important \$1/c\$ suppressed contributions that do not have such a simple
interpretation. We revisit the proof of a bound on \$łambda\_L\$ that emerges at
large \$c\$, focusing on CFT\$\_2\$ and explaining why our results do not conflict
with the analysis leading to the bound. We also comment on relationships
between chaos, scattering, causality, and bulk locality.
