I am looking for an English translation of "Les aspects probabilistes du contrôle stochastique" written by Nicole El Karoui, or knowledge whether it exists.


Other references with similar content on Snell envelopes are also appreciated.


Reference info: *Les aspects probabilistes du contrôle stochastique. (French) [The probabilistic aspects of stochastic control] Ninth Saint Flour Probability Summer School—1979 (Saint Flour, 1979), pp. 73–238,

English translation of "Les aspects probabilistes du contrôle stochastique"
There is no English translation of El Karoui's lecture notes, however her work on Snell envelopes is described in [Reflected Solutions of Backward SDE'S, and Related Obstacle Problems for PDE's](https://www.jstor.org/stable/2959608). For a text book treatment of Snell envelopes see [Methods of Mathematical Finance](https://www.springer.com/gp/book/9781493968145) by Karatzas and Shreve.
