摘要:
We consider a Brownian bridge on the hyperbolic plane with one extremity tending to infinity, in finite time. We show that the exact exponential rate according-to which this process concentrates around the geodesical segment joining the origin o to the moving extremity z is -rho(o, z), where rho stands for the hyperbolic distance. This improves a result of A. Eberle.
