Abstract
Let g \mathfrak {g} be a complex simple Lie algebra. A simple g \mathfrak {g} -module is called minimal if the associated variety of its annihilator ideal coincides with the closure of the minimal nilpotent coadjoint orbit. The main result of this paper is a classification of minimal highest weight modules for g \mathfrak {g} . This classification extends the work of Joseph [Ann. Sci. Γcole Norm. Sup. (4) 31 (1998), 17β45], which focused on categorizing minimal highest weight modules annihilated by completely prime ideals. Furthermore, we have determined the associated varieties of these modules. In other words, we have identified all possible weak quantizations of minimal orbital varieties.
