The Black-Litterman Model - Mathematical and Behavioral Finance Approaches Towards its Use in Practice, Mankert, 2006. Licentiate Thesis. This masters thesis was written by a student who implemented Black-Litterman for a Swedish Bank and noted that there wasn't a lot of good literature on the subject. She has some good detail on derivations of the core formulas of the Black-Litterman model, and provides new insights into the model by a novel derivation using sampling theory. She doesn't provide all the formulas needed and doesn't provide much in the way of worked examples. Still a very good source of information on the Black-Litterman model.
Modelo Black-Litterman Aplicacion a los FPO is a thesis by Mateo Eduardo Trujillo Segura on the application of the Black-Litterman model to Columbian Mandatory pension funds. It is a good reference to the Black-Litterman model in Spanish.
