In algebra, an integrable module (or integrable representation) of a Kac–Moody algebra (a certain infinite-dimensional Lie algebra) is a representation of such that (1) it is a sum of weight spaces and (2) the Chevalley generators of are locally nilpotent.[1] For example, the adjoint representation of a Kac–Moody algebra is integrable.[2]
