The goal is to approximate the law of a one-dimensional Brownian motion
conditioned not to cross fleeing boundaries when the time is big enough. To do so,
we will study the quasi-stationarity of the so-called renormalized Brownian motion.
After giving a short overview of the theory of quasi-stationarity, we will be interested
in the existence of some notions defined during the talk applied to this renormalized
