Properties of the Ornstein-Uhlenbeck bridge
Résumé
This paper is a study of the properties of the Ornstein-Uhlenbeck bridge. We derive its canonical decomposition using filtration enlargement techniques, and its Karhunen-Loève expansion for any value of the initial variance and mean-reversion parameter (or mean-repulsion if negative). Finally, we present an application to the optimal functional quantization of the Ornstein-Uhlenbeck bridge.
