Description
In this talk, we discuss the resilience to noise of collective behavior. Our main focus will be on a kinetic particle system developed by Cucker and Smale (2007). We establish key asymptotics for the first exit-time from a safety domain, namely Arrhenius' law and a Kramers-type law, which are well known for non-degenerate diffusions. This is joint work with Jean-François Jabir and Julian Tugaut.
